Abstract
PURPOSE: To increase suction efficiency of a pump, by opening the fluid feed line of a power steering pump device to a valve housing hole to which a spool valve is fitted and supercharging a fluid to a suction side of the pump.
CONSTITUTION: When rotary speed of a pump increases, its delivery flow rate also increases to open a valve passage and allow a surplus fluid to bypass a bypass 38. Fluid in a fluid tank 50 is turbulently sucked by a bypass flow at the connection point of a fluid feed line 39 and the bypass passage 38, and supercharge is performed to increase suction pressure of the pump. At this time, since the fluid feed line 39 communicated to the fluid tank 50 is opened to a valve housing hole 36 fitted with a flow regulating spool 43, then a meeting point of the bypass flow and feed flow is adjacently placed to a bypass passage opening part with the highest speed of the bypass flow, speed energy provided in the bypass flow can be applied to a maximum, thus suction efficiency to suction ports 25, 26 can be further increased.
