SU25633A1 - Air distributor for automatic single-wire air brake - Google Patents

Description

in the proposed air distribution for an automatic air brake, shown schematically in the drawing, the role of the distribution spool is massive, equipped with appropriate channels inside and several sealing rings outside the piston 1, moving in a cylindrical housing. This case is connected, first, to the main air conduit 4 pipe 9, having a branch 21 to the bottom of the hull, secondly with a brake cylinder 5 with an 8 in pipe in the third with a spare reservoir with pipe 10; In case 2, there is also a hole to the atmosphere, connected to channel 7 of the piston 1. The piston, balanced by the spring, has inside, besides the channel 7, also channel 6, axial with two radial branches to the holes for pipes 8 and 9 , and a channel of 13 d, l of communication with the pipe 9. The pressure of the spring, 20 on the piston 1 is regulated by a pressure screw 11. At the distributor, the set is applied; The safety, squeezing spring valve 16 between pipes 8 and 9, when charging, the air coming from the main air duct 4 along branch 21 of pipe 9 presses piston 1 from above and lowers it downwards, so that channel 13 comes up to pipe opening S, and slow filling of the reserve tank, 7 will be produced from the main air duct through pipe 9 through the return

valve 5, through channels 13 and 6 p through pipe i О until pressure in tank 17 is not equal to pressure in pipe 9f then piston 7 will rise upwards under the action of spring 20 and take the same position shown in the drawing.

When braking when the pressure in the main air duct 4 decreases in the pipe 9 and on top of the piston 1, the piston under pressure from the reserve tank rises up to the stop in the gasket 18, the radial branch channel 6 goes to the opening of the pipe 8, the air goes through it from the spare reservoir in the brake cylinder 3 and that will produce braking. When the pressure in tank 17 and 9 is equal, the piston 1 will drop to its former position, and channel 6, disconnected from pipe 8, will connect to pipe 9. Then the main air duct and the reserve tank will be replenished again through the driver's valve.

With an increase in pressure in the main air duct, and therefore in pipe 9 and above the piston, the latter lowers, channel 7 is connected to pipe 8, and through it air from the brake cylinder will be released to the atmosphere, and thus will be decelerated. The channel 13 of the piston 1 channel 13 approaches and through it the same pressure is established at the top and bottom of the piston, and with the help of its spring, 30 it will rise to its former normal position.

PRIORITY 3 a b ete n i.

.one. An air distributor for an automatic, single-wire air brake, characterized in that the role of the distribution gold is performed by the piston 2, equipped with appropriate channels and being constant d on one side under air pressure in the main air duct, and on the other - under pressure from the spring and spare air reservoir. 2. The form of execution of the air distributor ZO p. 1, characterized in that the channel 7 of the channels present in the piston 1 serves to communicate the brake cylinder with the atmosphere, channel 6.6

for communication of the reserve tank with the main air duct, through the open valve 5, and with the brake cylinder; ,, and channel 13 - for slow filling of the reserve tank from the main air duct through the same non-return valve 5, 3. The use in the air distributor of claim 1 and 2 of the pressure screw 71 ,. used to control the pressure of the spring 20 on the first 1-,

4. Application of the safety, slackening spring valve at item 1 - 3 at the air-distributor.
