Document Type and Number:
Japanese Patent JP2017110573
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide technique which can reduce torque for rotating and driving a vane pump device.SOLUTION: A hydraulic device includes: a vane pump 1 having a pump unit for delivering oil at a first delivery pressure and oil at a second delivery pressure lower than the first delivery pressure, and a housing which stores the pump unit and has a high pressure side delivery port 117 for delivering the oil at the first delivery pressure delivered from the pump unit to the outside and a low pressure side delivery port 118 for delivering the oil at the second delivery pressure to the outside; a high pressure side guide passage 503 for guiding the oil delivered from the high pressure side delivery port 117 of the vane pump 1 to a fluid apparatus 501; a low pressure side guide passage 506 for guiding the oil delivered from the low pressure side delivery port 118 to a lubrication object portion 505 different from the fluid apparatus 501; and a selector valve 508 provided in the low pressure side guide passage 506 and switching whether the oil delivered from the low pressure side delivery port 118 is guided to the lubrication object portion 505 or is guided to the fluid apparatus 501.SELECTED DRAWING: Figure 19
