Abstract: A vane pump includes a rotor; a plurality of vanes; a cam ring; a second side plate; a suction port provided in the second side plate, the suction port being configured to guide working fluid to the pump chambers; a pump cover arranged so as to sandwich the second side plate with the cam ring; and a low-pressure chamber formed in the pump cover, the low-pressure chamber having an opening portion communicating with the suction port. The suction port is arranged so as to be shifted towards a forward side of in a rotating direction of the rotor with respect to the opening portion of the low-pressure chamber.

Abstract: A control valve includes a seat portion through which the fluid passes, a poppet which has a valve body portion and is configured to move relative to the seat portion, and a poppet throttle passage defined between the seat portion and the valve body portion. The poppet throttle passage is formed to gradually increase a flow passage area in a horizontal cross-section perpendicular to center axes of the seat portion and the valve body portion from an upstream side to a downstream side.
