Página 57 - The air valves are simple poppet or check valves, which seat by gravity while the pistons wait, and therefore are not liable to pound themselves to pieces. (The pistons of one side rest while the pistons of the other side are in motion. ) The operation is as follows: In the position shown, the air piston in cylinder (4) has...
Página 61 - When piston (22) reaches the end of its downward stroke, the plate (20) strikes the tappet on valve stem (7) and moves valve (5) to its lowest position, thus uncovering port (26) and admitting steam through port (26) to the lower side of piston (21), thus causing piston (21) to rise and compress the air which is in cylinder (4) through valve (11) into upper part of cylinder (3). Just as piston (21) completes its stroke, its plate (20) strikes. the tappet on...
Página 66 - The slide valve (38 ) can remain stationary while the piston (40 ) returns part way and closes graduating valve (48 ), as the abutments that move valve (38 ) are farther apart than the length of the valve. The operation is as follows: Air from the train-pipe passes to cylinder (A), through charging groove (B) and passage (C) to chamber (D), and thence through passage (E) into the auxiliary reservoir. When the train-pipe pressure is reduced, the piston (40 ) moves its full stroke, first shutting off...

The slide valve 38 can remain stationary while the piston 40 returns part way and causes graduating valve 48 to cover the service port, as the abutments that move valve 38 are farther apart than the, length of the valve. T*he. operation is. as follows: Air from the train pipe passes to cylinder A, through charging groove В and passage С to chamber D, and thence through passage E into the auxiliary reservoir.
