Abstract
Hydraulic device equipped with triposicionable valve, characterized in that the impeller plunger has a port that opens into a cavity, interleaved between two unidirectional valves, one of which is the one that sends the fluid to the cylinder and the other where it receives the fluid from the reservoir; this reception is carried out through a valve that interconnects with the fluid reservoir.
