Title:
オイル供給システム
Document Type and Number:
Japanese Patent JP6430715
Kind Code:
B2
Abstract:
An oil supply system of the present invention supplies oil stored in an oil storage unit (20) to an operating unit (10) and comprises: a main pump (30) driven in conjunction with the driving of the operating unit (10) to suction and pressurize the oil from the oil storage unit (20) and to discharge the oil to the operating unit (10); and a sub-pump (50) driven by a dedicated driving source (53) in an operation region under a predetermined condition of the operating unit (10) to suction and pressurize the oil from the oil storage unit (20) and to discharge the oil containing bubbles to the oil storage unit (20) while pressurizing and supplying the remaining oil to the upstream side of the main pump (30). This allows the supply of the oil from which bubbles have been separated only under a required condition, thereby reducing torque loss and power consumption.
