HYDRAULIC TYPE WORKING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic type working system in which the energy consumption of a pump is reduced by reducing the internal pressure of a slave cylinder only to such a degree as to admit re-engagement of a clutch. SOLUTION: The second check valve 36 is installed between a pump 16 and vessel 14 for hindering the fluid from flowing between them, and a solenoid type control valve 20 is installed, which takes two positions; the first to connect a pressure accumulator 12 to a slave cylinder 34 and the second position to connect the slave cylinder 34 to a point between the pump 16 and the second check valve 36.
