through the process 3 (Fig. 3) is directly communicated with the main air duct. A distributing spool 4 is placed between the porlen plates G and pressed against the mirror with a spring 5. The chamber Og of channels 6 and 7 is connected to the camera & 4b locking KJia.Pana 47 brake cylinder. Movement of the piston 1 in the direction of the chamber ai is limited to its stops in the spring valve 8, the chamber 9 of which, via channel 10, communicates with the camera 2 The movement of the piston in the direction of the chamber s is limited by the stop e / o to the locking valve 11, fixedly pressed to its saddle 12, and the chamber 13 of this valve is directly communicated via the channel 14 with the reserve tank 1 (FIG. 6). The pressure regulator chamber B (Fig. 3) is also divided into three parts by its differential valve piston 15: an Oi-constant pressure chamber, 1MVRU (2 D 1®nia, a hot air line and a chamber (7z-pressure of the brake cylinder. In chamber 6i has a spool 10, reinforced on the end of the piston rod DB and intended for communication and separation of chamber 6i with the atmosphere, the chamber 62 using channel 17 always

communicated with the camera a, i finally, the camera 5z channel 18 communicated with the brake cylinder. The upward movement of the piston 15 is limited by the stop of the valve 22 p, its seat, and the valve with its guide sleeve 23 rests on the valve 19 and can communicate the chamber Jj with the chamber 20, which is directly connected to the chamber through the stop by the channel 21 it into shock buffer 24. In chamber b (Fig. 2) of differential braking, there is a differential piston 25, chamber ei and which, using channels 44 and 48, communicate with the brake cylinder, and camera in channel 26 (Fig. 3) always communicates with the atmosphere. The upward movement of the piston 2b is limited by the stop in / its valve seat 27, closing the channel 28, t (L; it is separated from the channel 44; the downward movement of the piston is limited by its stop in the valve 29, the chamber 30 of which is directly connected to the camera through channel 31 2- Differential piston 32 (Fig. 4) is placed in the braking mode chamber T, which divides it into three parts: the chamber 3, connected via channel 33 to the safaHbiM reservoir (fig. B), and the camera KafaanoM 34 connected to the brake cylinder , and a camera, which can be through channels 35, 36 and 37 is connected to chamber 2 or channel 35 and channels 38 and 39 in the cork of the crane 42- with the a sphere. The movement of the shaft 32 towards the chamber g- is limited by its focus on the intermediate valve 40 whose chamber 43 .. is channel 44 (Fig. 2) is connected to the chamber and channel with. The chamber 46 (Fig. 5) of the valve 47; the movement of the piston towards the chamber gj is limited by its abutment into the cover 41.

When charging the braking devices (which corresponds to the position of tempering the brakes), air from the main air duct 10 (Fig. 6) through the process 3 (Fig. 3) enters the chamber "9 of the piston 1 and from here through the channel. 17 (. 3) into the chamber 2 of the pressure regulator and through the channels 62 and 63 (FIG. 2) through the passage 61 of FIG. 4) —in the auxiliary tank of FIG. 6). By air pressure, the piston 1 moves toward the chamber and aa 15 pressure regulator toward the chamber (Hey valve: 22 with its protrusion / 23 although it raises valve 19, but tav as valve 22 in this case will be tightly pressed to its seat , then chamber 20 will be shared from; chamber 5i. With its movement, piston 1 will move from the opening 4, which is capacitive 49 so6; and channel 28 with atmospheric channel 50. well air from the brake cylinder through channel 34 (Fig. 4 ) through the intermediate valve 40, the chamber 43j channels 44 and 51 (Fig. 2), as well as through the valve 52. ka S 53, 1-8 and 28 (Fig. 3) will escape to the atmosphere. Simultaneously, the piston 1 will depress the valve 8 with its rod 14 and the air from the cocker 9, and through the channel from chamber ya enter chamber A. from where channel 2 Fig. 2, 3) into the pressure regulator chamber Oj, as a result of which the pressure on the disk of larger diameter of the piston - 1 and on the piston 15 of the pressure / will be balanced. But since, chamber a of piston 1 and cam, and a piston. 15 will be associated with the atmosphere, then the air pressure from the chambers "side and 5 hours" will move these pistons a little: piston 1 In the direction of the chamber az, a-pist-15, in the direction of chamber b-, (position-; nor, shown in Fig. 2, 3). Then the valve 8 under the action of its spring. In this case, channel 28, and then also the brake cylinder, with atmosphere, will also be reported to children on its saddle and will stop the access of air to the chamber and O. Gold. If, in any case: the pressure in the chamber / pax "1 and O is reduced (from leakage through the connections and t, p.), The piston 1 is pressure from the chamber side," 2 trans. It is placed in the direction of the chamber and HL then with valve 14 again depress the valve 8 and the air from the chamber "2-fill-up, this leakage, all the time maintain a certain pressure in the chambers ai and (Jj.

In the case of a pressure increase in 1sam, pax, and 5i (for example, valve 8, | 9, etc.), the pimpgen 15 under pressure of air from the side of the chamber Oj goes down, moving, and zolotnk 16, which, with its notch 54, will communicate channel 2 with an atmospheric anal 55 and, as soon as the pressure in i pax 5i and Oi is set to not 6,

The air duct, and therefore, also in chambers "2 and (Jo, up to about 0.3 at, which corresponds to the initial braking, pistons 1 and 15, due to the imbalance of their equilibrium state, moves - first towards kamvry from 11, and in the direction of the chamber bz, while pressing the shock buffer 24 and standing in its lower position. At the same time, the piston 15 will also move, e down and the spool 16, which is common

Camera Oi from the atmosphere. | and the piston 1 1 turns the slide valve 4 towards the chamber of Oz, which opens the brake cylinder with the atmosphere and blocks the channels 62 and 63 going into the auxiliary reservoir, and communicates channel 28 with channel 60 with the help of the channel 60. 57 and channel 58 (FIG. 3) with a spare tank, as a result of which the blow out of the spare tank through channels 60 and 28 through valve 27 ji I will not enter the large channel 51 into chamber i of the piston 25 by pressing down the piston with pressure. channel 44. enters the chamber 43 and hence the intermediate valve 40 (Fig. 4) through the channel 34-n in the brake; ilindr. In turn, the piston 25 will press the air out of 29 h. Air, through the chamber 30 through the channel 31 will be nocTjnaTis. from camera aai a. with and from the main vozduhprbvbda,

into the chamber, and from here along channels 48 and 44 into the brake cylinder. In this way,

, into the brake cylinder is to proceed in two ways: the first is from the emergency tank and the second is from the main air line, as a result of which the pressure in the brake cylinder will be released,. and in the main air duct there will be an additional negative pressure of the main air, wire under each tornado unit during the initial deceleration, which causes the work of the following air distributors in the train, causing simultaneous (continuous) braking action the entire length of the train. With a steady pressure in the brake cylinder, such a fluid (3 pressure will be established in the chamber "3 of the piston 25 and the air pressure acting in this way over a large area of the piston 25 will move it up (according to the drawing), the valve 27 will block its channel 28 and thereby stop access to the brake cylinder through a wide channel, and the valve 29 under the action of its spring closes and stops the air from the chamber. "2, and hence from the main air duct, into the brake cylinder: ind. Thus, the message of the reserve tank during subsequent braking TC only through narrow Canadian 51, why in this case the pressure in the brake cylinder will increase slowly (smoothly), which ensures smooth braking of the engine train;

The air entering the brake cylinder through chamber 43, channel 45, as well as valve 46 chamber 46 and canal 7 will pass into the chamber and the pistons: 1, the pressure in the chamber will increase and the piston 1 will be balanced, which is under pressure with The camera sides will "smoothly move toward the chamber" j, while the spool 4 will only block channel 28 ,. dissociating it from channel 60, and, therefore, separating the brake cylinder from the spare tank | 1. At the same time, air from the brake cylinder of the Cherkes system through channels 28 and 18 (Fig. 3) will also flow into pressure measure Oz. With a steady pressure in this chamber, the piston 15 will move upwards and will take up its initial position, shown in FIG. 3. If in this case in the chamber ui piston 1 for any reason. If the air pressure is lowered (a leakage, etc.), it will also be lowered in the chamber Oi, and the piston 15 will press down on it from the side of the chamber b and Oz will lift up and the valve 22 will open its valve 23 19, as a result of which the air from chamber 6-2 (as well as from both a and from the train pipe), through channel 21, does not cut the chamber 20

enters chamber 6i as well. hence j is in the ffj camera, and as soon as in these cameras, ipax is installed. normal - DELIVERY, | the piston 15 will again occupy its initial position and the valve 19 will, under the pressure of its spring, stop the air from coming from the chamber Oz to the chambers j and «i. If in the chamber% the pressure will increase; against the normal (skip valves 8, 19, etc.), it also rises in the chamber Oj, and then the piston 15 drops down, will move the spool 16,. which in this case by means of its own channel 2, and, consequently, the chambers 5i and aj, with the atmosphere, and as soon as the normal pressure is established in these chambers, the piston 15 will return to its original position.

If, with a steady pressure in the brake peel, it subsequently drops (as a result of a pass, the flow pass piston in the connections, etc.), then it will also be lowered in the chamber of the piston 1, | which, under pressure from the side of the chamber “i” (where, as was said above, the pressure is always automatically maintained normal) is reversed to the side of chamber i, with echo, the sump 4 will again report channel 28 with channel 60, due to leakage of the brake cylinder The automatic filling tank is filled by the pressure of the reserve tank, and the air flow rate from the reserve tank will also be replenished through the spare valve 56, {Fig. 3) from the main air duct and from the main reservoir, which gives a real flow of the torus, moznon, systems. -.

In case you need to produce

a quick stop of the train (for example, when traveling, signaling an accident in a train), a driver (help, crane driver) or a conductor (a help crane) makes a sharp drop in pressure in the main air duct, and, therefore, in chamber piston 1, which iodine pressure on

from the side of the camera to quickly move to the side of the camera "3, with etots. spool 4 times () bs; it brake 1Y ts pdr with atmosphere, and with the help of its notch b4: (sketch mirror 2 holders; 21) and channel 65, as well as notch; 59 Sobp it channel 62 and 63, coming from the auxiliary rezbrvuara, with the channel: 28, nd. In addition, the air from the auxiliary tank through channel 61 (Fig. 4) will be transferred to the brake cylinder in the specified ways. Simultaneously with this, the piston 1 will open channel 6 with its small disk, as a result of which. and consequently, the main duct pz, through the channel 6, the valve 47, through the chamber 46 through the channel 45 will flow into the chamber 43, and from here into the brake cylinder. In addition, the same piston 1 will depress the shut-off valve 11 of the sealing tank; then the air from the reserve tank through chamber 14 through the valve), valve 11, P9 channel 7 enters the chamber 46 of the valves 47 and from here to the brake cylinder, thus entering the brake cylinder the air proceeds in three ways: - from the main air duct, from the reserve |% reserve and auxiliary reserve, as a result of which the pressure in it must be restored very quickly. In order in this case to warn the capable, to be: ro, arbitrary release of the brake, owing to - very fast (noBi)) pressure in the brake cylinder -. consequently, l in the chamber ig, in the spool 4 there is an additional side cut 66 (Fig. 2 - sketch), which in this case is set against channel 07, going to. the atmosphere. Then, the air: from / chamber yo, and consequently from the main air duct, through section 66 and channel 67 goes into the atmosphere, all the time maintaining the vacuum in this chamber of the main air duct ahead of the increase in pressure in the chamber. of the fact that in this case, according to each brake unit, an additional depression of the main air duct occurs, with which the air reaches the brake region. , and part of the atmosphere, and the vacuum; the main air duct also occurs quickly; like the filling of TopMO3Hibix cylinders.

The brakes act on all over the train at the same time, i.e. continuously ./

 ; If it is necessary to make a gradual release of the brakes, the driver places the crane's knob in the position corresponding to the graduation of tempering, h: it achieves a smooth and definite increase in pressure in the main air. drive and therefore s camera a

 At the same time, the piston 1 will smoothly move to the side of the chamber “iv and move the spool 4 with it, which will use the recess 49 and channels 28 and -50 to communicate the brake chi (the atmosphere with the reserve, previously working it from the reserve tank. As a result pressure is in brake

, the cylinder, and therefore through the corresponding channels (as mentioned above) and in chamber az, the pressure on the piston (1, which under pressure on it from / side of the chamber "1 and the spool 4 will block the release of air from the brake cylinder into the atmosphere, lowering the pressure in the pressure at the main air duct. V When an emergency release of the brake

MajODEHHHCT uses a short wide channel to communicate the main air flow control system with the main reservoir, in the result of which. the pressure of the air in the duct, and consequently in the chamber “from the air distributor, quickly spans the piston 1 and moves the pistol 1 along with the deflector to the side flSj; at the same time, the gold cylinder 4, boosters the brake cylinder with the atmosphere, will also open Katsaly 62 and 63 and the air from the auxiliary tank will flow through these channels into the chamber a-, and from there to the Main air duct, quickly restore the pressure in it and cause the action of train air distributors and thus ensuring neV intermittent braking of the train length, available in the air distributor

the camera, braking is intended for two different modes of operation of a freight car in a loaded and otherwise its condition, in order to set the deceleration mode to

the empty car, the chamber gj (fig. 4) communicates with the atmosphere by means of the plug, and the kaiiiepa 81 canalol 33 is always connected to the spare tank, then the piston 32 under pressure from the side of chamber 2i moves and squeezes intermediate valve 40, in turn, opens it. When braking cylinder enters the air enters, also c. the chamber 82 of the piston 32, and since the area of the stern from the side of the larger dibka will be larger, then at a steady pressure j6 of the brake:; indre, dispersed om- for braking the empty wagon, by air pressure from the chamber порш, the piston 32 leresves towards the chamber 8i, at the same time, the valve 40 closes under the action of its spring and the CR will prevent air from entering the brake cylinder, although at the same time it continues to flow d:, / tori. If, in this case, the pressure in the brake cylinder drops (piston admission, etc.), it will also fall in chamber G. Then the piston 32 under pressure on it from the side of chamber gj will again move toward the chamber Z3 and Opens the valve 40. Air from chamber 43, and therefore from chamber a, will go to the brake cylinder, the whole result of which donating in the osg chamber will decrease and the piston 1 will be activated, which will automatically compensate for the indicated leakage in the brake valve cylinder as described earlier. In order to set the braking mode of the sullen wagon, it is necessary to deliver the stopper of the crane 42 to the position shown in FIG. 4: at this, m air from chamber 2j will flow through channels 37, 36, and 35 to Ka. / Mugs, as a result of which the pressure of this air on the small disk will be balanced, and the pressure on the large disk will move the piston 32 towards the chamber gj and open valve 40. In this case, both with full service braking and emergency, the brake pressure of the cylinder. will be equal to the pressure of the reserve tank.

A valve 68 in the diffuser, 68 (Fig. 3), makes it possible to slow down (for freight trains) or to speed up (for passenger trains) the braking process. In passenger trains, the crane handle 68 is placed in the position indicated in the drawing, with the air entering the brake cylinder through channel 28 not only passing through hole 51 (FIG. 2), but through channel 69, notch 70 in the crane stopper 68 and through channel 71 (FIG. 3) to chamber b, and from there via channel 44 to brake cylinder. With a freight train, the handle of the crane 68 rotates 90 °, at which the shackles 69 and .71 will be separately disconnected, and therefore will be stopped in the brake cylinder, as it was said before, after the initial braking will only pass through the narrow channel 51 And FIG. I PRIORDS AREA The air distributor for an automatized, single-conductor torus-; a mosaic that implies a non-sys- tem, continuity of action, stepped braking and tempering, characterized by the use of 4 placed in a common case of the battery, with a width of 1 ,. 25, 32 and spring valves 11, 8, 40. and 47 (Figs. 2, 3 and 4) j, the corresponding movements of which and the associated switchings in the air distributor housing of the air ducts and chambers are intended for the indicated braking action.
