Abstract (en)
[origin: EP0600202A1] Control valve device having a working piston, a main valve slide (41), the smaller piston surface (43) of which faces a compressed-air storage space (21) and the larger piston surface (45) of which faces a main control space (44), an auxiliary valve slide (42), the first active surface (72) of which can be connected by means of a triggering valve (98) to atmosphere or compressed-air storage space to move the main valve slide (41) into the open position, and a second active surface (73) is connected to a piston stroke space (84) to move the main valve slide (41) into the closed position, the auxiliary valve slide (42) being moved back when the pressure at its second active surface (73) falls below a preset value, this active surface (73) being connected to a reversing valve (79) which is connected to atmosphere when the trigger (23) is not actuated and is closed upon actuation, and the trigger (23) having a first movement path and after a second movement path actuating the reversing valve (79), while the triggering valve (98) remains activated, the reversing valve (79) having a push rod (103) which, upon displacement beyond an open position closes an outlet opening (104) connecting the second active surface (73) to atmosphere, and which upon trigger actuation over the second movement path is pushed away beyond the open position, being stressed for a movement to the open position. <IMAGE>
