Description

In the proposed steam distribution mechanism for steam engines, driven by a working piston, in order to eliminate a whole range of leverage systems for moving spools, two steam boxes, communicating with each other by a channel, crossmembers connected by rods to the rocker and inlet valves, each rigidly connected with a corresponding exhaust valve, which crossbars are driven by blows of a biconical working piston on rollers of rods fastened to said crossbars.

The proposed steam distribution mechanism is depicted in a schematic drawing in longitudinal section.

Above the working cylinder 1, having a biconical piston 2, two steam boxes 4 and 5 are interconnected by a channel 23, in which crossbars b and 17 are placed, connected by rods 18 and 19 with a bore. the rods b and 17 are attached rods 8 and 11 with rollers at the ends extending half a meter into cylinder 1, and connected to inlet valves 12 and 14, with which outlet valves 22 and 21 are rigidly connected, opening channels 16 and 15 for exit a pair of cylinder.

The action of the proposed mechanism is as follows.

Steam from the boiler through channels 3 and 23 enters boxes 4 and 5 and rushes through channel 12 opened by valve 12 into cylinder 1, which causes piston 2 to move to the left and, striking the roller of rod 11, raises the latter, which in turn raises the cross member 17, and through the rod 19 and the left end of the rocker arm 20, lowering its right end. With the lift of the crossbar 17, the valves 14 and 21 are lifted by means of the rod 14 and the steam, directed along channel 13 to the left side of the cylinder, drives the piston 2 to the right. While the piston, acting on the roller of the rod 11, lowered the right end of the rocker arm, the cross member b also lowered and together with it the rods 8 and 7, causing the valve 12 to close the steam inlet channel 12 and the valve 22 connected to the valve 12 channel for the output of that pair. Moving right, the piston strikes the roller “8”, lifts the latter, and with it the crossbar b with the rod 7, causing valve 22 to close the exhaust channel 16, and valve-14 opens channel 12 for fresh steam that drives the piston to the left etc.

The subject of the patent.

A steam distribution mechanism for steam engines, driven by a working piston, characterized by the use of crossbars B and 17 placed in steam boxes 4 and 5, connected by a rocker arm 20 between themselves and rods 7 and 14 by inlet valves 12 and 14, with which rigidly discharged valves 21 and 22, which crossbars are driven by blows of the biconical piston 2 against the rollers of the rods 8 and 11, fastened to the above crossbars.
