摘要
The invention proposes a hydraulic device of the kind including a cylinder in which a piston is mounted for sliding in leaktight fashion in the body of the cylinder so as to delimit at least one hydraulic chamber intended to be linked to a hydraulic circuit, and is linked to the front extremity of an actuating rod which projects axially rearwardly outside the cylinder body and on which an actuating force can be applied in order to cause forward displacement of the piston counter to a return force applied to the piston. The device includes a temporary end stop which limits the forward displacement of the piston and which intervenes until the piston is first actuated by means of the actuating rod. The invention is applicable to a hydraulic cylinder for the control of motor-vehicle equipment.
