FLUID MACHINE WITH WET CLUTCH DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a stable pressure source without causing enlargement of a compressor so as to positively actuate a wet clutch device. SOLUTION: A driven side clutch plate 11 is arranged opposedly to a driving side clutch plate 12 rotated by the rotation of a driving shaft 5, and an operating part of a compressor 1 is connected to the driven side clutch plate 11. A control piston 8 is provided to apply pressing force to the driving side clutch plate 12 and driven side clutch plate 11 so as to pressure-fit both clutch plates 11, 12 and to connect them integrally, and an auxiliary pump 15 for applying control pressure to a back pressure chamber 8a of the control piston 8 is actuated by the rotation of the driving shaft 5. Oil delivery pressure of the auxiliary pump 15 is controlled by a solenoid valve 25 and a relief valve 21a so as to increase/decrease control pressure to the back pressure chamber 8a. Both clutch plates 11, 12 are intermitted by the increase/decrease of this control pressure.
