Abstract

In the case of an actuating cylinder, particularly a double-acting door-lock cylinder for actuating doors of rail vehicles, a bolt mechanism is necessary, which with total reliability prevents opening of the doors when the train is in motion. For bolting the piston rod (3) of the actuating cylinder connected to the door locking mechanism and able to be actuated by a piston, a bolt (9), movable in a transverse direction of the piston rod (3), is provided, which is supported on both sides of the longitudinal axis of the piston rod (3) in guides of the housing (5) accommodating it, the piston rod passing through a bore of sufficient width running in the bolt (9) in a transverse direction to this. The bolt (9) can be actuated by compressed air against spring force, that is it can be shifted into its bolting position, the pressure acting on the bolt being monitored by a valve (15), which can be actuated by a section of the piston rod (3). In the locked position a shoulder (31) of the bolt (9) is in collision with the displacement travel of the piston rod, the withdrawal of which from the locking mechanism can thereby be prevented. <IMAGE>
