Claims

[Scope of utility model registration request]

Controlling the pressure fluid discharged from the discharge port by a flow regulating valve slidably fitted in the valve housing hole, and supplying a constant flow rate of pressure fluid to a power steering device communicating with the valve housing hole;
Surplus flow is bypassed to the bypass passage that opens to the valve housing hole, and further, this surplus flow is combined with fluid from a fluid supply path communicating with the fluid tank in the middle of the bypass passage, and then returned to the suction port. In the pump device, before the flow rate adjustment valve opens the bypass passage, an auxiliary passage that communicates the bypass passage with the valve chamber communicating with the discharge port is connected to the fitting portion of the valve storage hole and the flow rate adjustment valve. A pump device characterized in that it is formed as follows.
