    IPC: F16F9/348 ,  F16F9/512

    Abstract: A valve includes: a leaf valve component; an opposing surface opposing to the component, the opposing surface being configured to prohibit passage of working fluid in a liquid path where the component is arranged; and a seating surface configured to come into contact with the component and prohibit passage of the working fluid in the liquid path in a case in which the component is elastically deformed by a predetermined amount, wherein, in an allowing stroke, during which the passage of the working fluid is allowed, the component is elastically deformed in a direction away from the seating surface so as to allow the passage of the working fluid, and the predetermined amount is set such that the component comes into contact with the seating surface when the speed of a piston exceeds an upper limit value of a predetermined normal range in a restricting stroke.

    Abstract: A vane pump includes: pump chambers formed by a rotor, a cam ring, and vanes; a first suction port that guides working fluid guided by a suction passage to the pump chambers; a second suction port that guides the working fluid guided from the suction passage through a communication passage to the pump chambers; and a return passage to which excessive fluid of the working fluid discharged from the pump chambers is guided. The return passage has: a body-internal passage through which the excessive fluid flows along an axis direction at an outer side of the cam ring in a radial direction; and a turning passage that reverses the excessive fluid guided through the body-internal passage towards the second suction port.
