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.

Abstract: A cap with electromagnetic proportional valve, includes a pilot cap mounted on a valve housing and defining a pilot chamber, and an electromagnetic proportional valve mounted on the pilot cap and adapted to control a pressure of a working fluid supplied to the pilot chamber. The pilot cap includes a supply port into which a working fluid of a fluid pressure supply source is supplied, a discharge port from which the working fluid is discharged to the tank, a primary pressure passage which leads the working fluid at a primary pressure to the electromagnetic proportional valve from the supply port, a secondary pressure passage which leads the working fluid whose pressure is reduced to a secondary pressure by the electromagnetic proportional valve to the pilot chamber, and a drain passage which leads the working fluid discharged from the electromagnetic proportional valve to the discharge port.
