Compact vane pump with mixed suction and return flows |
摘要 |
A vane pump can effectively utilize the total quantity of a working fluid delivered from a vane section. The pump can be used for fluid pressure operated equipment requiring a high flow rate, does not create torque loss due to a throttle valve, and can prevent the occurrence of cavitation caused by a shortage of suction. The vane pump pressurizes and delivers a working fluid through a vane section. A returning working fluid flowing through a return port is throttled and accelerated by a throttle valve, and a working fluid sent from a suction port is attracted by the accelerated returning working fluid so that the returning working fluid and the working fluid sent from a tank are sent into the vane section.
