Abstract

Improvements in reciprocating hydraulic apparatus, characterized by comprising an edge element and a hydraulically actuated and oscillating type distribution valve with two positions, in each of which connects one of the ram's working chambers to a generator of working fluid under pressure, while connecting the other working chamber of the ram to a discharge step; the oscillating type distribution valve is prepared to move in opposite directions by pressurized fluid acting respectively on opposite faces of the valve piston in two chambers; the ram element contains parts that control passages that open inside the ram cylinder, in positions such that said element acts as a valve that, towards the end of its movement with respect to the cylinder, in each of the directions, under the pressure of the working fluid in the appropriate chamber of the working chambers, connects this working chamber to one of the pressure chambers of the distribution valve, while connecting the other pressure chamber of the distribution valve to a discharge step to give rise to the movement of the distributor valve from one position to another and, therefore, to produce the inversion in the ram elements.
