The end-of-stroke expander (1) for a piston-type pressure converter (2) of which the emitter cylinder (3) and the receiver cylinder (4) respectively define an emitter chamber (9) and a receiver chamber (10), comprises an expansion emitter cylinder (12) which communicates with the receiver chamber (10) and in which cylinder there may move an expansion emitter drive piston (14) mechanically connected by a progressive lever-effect transmission (11) to an expansion receiver pump piston (15) which can move in an expansion receiver cylinder (13), said transmission (11) being intended so that when the expansion emitter drive piston (14) is at top dead centre, the expansion receiver pump piston (15) is at bottom dead centre, and vice versa, whereas an expansion unblocking actuator (30) can set said transmission (11) in motion. |
