Hydraulic controller with double-acting converter - has component separating primary and secondary sides of changeover circuit

摘要

The hydraulic controller comprises a double-acting hydro-mechanical converter (3) generating reciprocating movement. It has a circuit (2) with a changeover valve (14) alternately connecting the converter chambers (8,9) to the pressure supply and discharge unions (11,12). The primary side of the circuit connected to the first union (11) is separated by a component (13) from the secondary side connected to the second union. There is a hydraulically solid connection on both sides between the component and the converter. USE/ADVANTAGE - Efficiency and reliable operation of hydraulic control system.
