動力舵取装置用ポンプ。 The pressure fluid discharged from the oil pump is sent from the supply passage to the power steering device via the throttle passage,
The excess flow is returned to the suction side of the oil pump through the bypass passage by a flow rate adjustment spool valve that adjusts the opening degree of the bypass passage, and a biasing force is applied to counter the pressure difference before and after the throttle passage. In a pump for a power steering device in which a spring is applied to the flow rate adjusting spool valve, a valve driving member configured to displace the flow rate adjusting spool valve is disposed in parallel with the spring, and the valve driving member is configured to displace the flow rate adjusting spool valve. is made of shape memory alloy,
A pump for a power steering device, characterized in that the shape memory alloy stores a state in which it is in an expanded state as a secondary permanent deformation processing state and a state in which it is in a contracted state as a memory state before deformation.
