Abstract
The reversible hydraulic pressure converter (1) employing tubular valves includes a medium-pressure stage (44) consisting of a medium-pressure cylinder (2) and a double-acting medium-pressure piston (3) the position of which is sent to a control computer of the converter (19) by a piston position sensor (14), the cylinder (2) and the piston (3) forming two medium-pressure chambers (5) that can be placed in communication with a medium-pressure inlet-outlet circuit (15) by at least one tubular valve (12), the converter (1) also including two high-pressure cylinders (9) each cooperating with a high-pressure piston (8) of smaller diameter and defining two high-pressure chambers (11) that can be placed in communication with a high-pressure inlet-outlet circuit (16) by at least one tubular valve (12), each of the various tubular valves (12) cooperating with an independent valve actuator (13).
