Reversible hydraulic pressure transducer using a valve tube

摘要

The reversible hydraulic pressure transducer (1) using a valve tube comprises an intermediate pressure stage (44), which consists of an intermediate pressure cylinder (2) and a double acting intermediate pressure piston (3). The position of the double acting intermediate pressure piston (3) is sent by the piston position sensor (14) to the control computer of the converter (19). The cylinder (2) and the piston (3) form two intermediate pressure chambers (5), which are connected to an intermediate pressure inflow / outflow circuit (at least one valve pipe (12)). 15) can be placed in communication with. Said converter (1) also comprises two high-pressure cylinders (9), each high-pressure cylinder (9) of which cooperates with a smaller diameter high-pressure piston (8), Two high pressure chambers (11) are defined. These high pressure chambers (11) can be placed in communication with the high pressure inflow / outflow circuit (16) by at least one valve tube (12). One valve tube (12) of the various valve tubes (12) cooperates with an independent valve actuator (13). [Selection] Figure 1
