Document Type and Number:
Japanese Patent JP6509860
Kind Code:
B2
Abstract:
The reversible hydraulic pressure converter with tubular valves (1) comprises a medium-pressure stage (44) consisting of a medium-pressure cylinder (2) and a medium-pressure double-acting piston (3), the position of which is transmitted to a management computer of the converter (19) by a piston position sensor (14), said cylinder (2) and said piston (3) forming two medium-pressure chambers (5) that can be brought into connection with a medium-pressure inlet/outlet circuit (15) by at least one tubular valve (12), said converter (1) also comprising two high-pressure cylinders (9) each engaging with a high-pressure piston (8) having a smaller diameter and defining two high-pressure chambers (11) that can be brought into connection with a high-pressure inlet/outlet circuit (18) by at least one tubular valve (12), the various tubular valves (12) each cooperating with a separate valve actuator (13).
