Hydraulic clutch device

Abstract:

A hydraulic clutch device comprises an oil pump (7), a pressure regulating valve (8) for pressure-regulating oil discharged from the oil pump, and a hydraulic clutch (5) arranged in a power transmission route through which motive power is transmitted along a rotation shaft (4) from the power transmission part (2, 3), and engaged by the oil pressure-regulated by the pressure regulating valve. The pressure regulating valve is located on a downstream side in an oil flowing direction of the hydraulic clutch and arranged in the vicinity of an opposite side to the power transmission part in the axial direction of the rotation shaft with respect to the hydraulic clutch. With this configuration, it is possible to dispense with a pressure regulating valve arranged between a power transmission part and a hydraulic clutch and a valve body integrally provided with the pressure regulating valve in a conventional hydraulic clutch device.
