    Abstract: The drive part for converting the revolution movement to the wobble movement is composed of the shaft for transmitting the drive force from outside, the swash plate rotated by the shaft and the wobble plate for converting the revolution movement of the swash plate to the wobble movement. Plural pistons are reciprocated in responsive to the wobble movement of the wobble plate. The crank room containing the swash plate, the wobble plate and the piston is separated into the fuel room and the drive room by the bellows. The bearings for transmitting the drive force between the shaft in the drive room and the swash plate, and the bearing for transmitting the drive force between the swash plate and the wobble plate are placed inside the drive room in order to lubricate the bearings. By arranging plural pistons inside the fuel room, the fuel is forced to be taken in and discharged by the reciprocate movement of the individual pistons.

    Abstract: A high-pressure fuel supply pump includes a discharge valve, which is a non-return valve between a pressurizing chamber and a discharge port. The discharge valve includes a valve body housing, a discharge valve spring, a valve body and a seat member. The discharge valve is a flat valve. When the valve is opened, a flow of fuel moving from the pressurizing chamber and axially colliding with the valve body is radially distributed in the radial direction of the valve body to become a flow directly moving the discharge ports and a flow colliding with an inner wall of the valve body housing before moving toward the discharge ports and then in a circumferential direction of the valve body.

    Abstract: A high-pressure fuel supply pump mounted with a discharge valve that can reduce an influence of noise caused by a valve body-circumferential flow and a discharge valve unit used therein. The high-pressure fuel supply pump includes a discharge valve (8) which is a non-return valve between a pressurizing chamber (11) and a discharge port (13). The discharge valve (8) includes a valve body housing (8d), a discharge valve spring (8c), a valve body (8b) and a seat member (8a). The discharge valve (8) is a flat valve. When the valve is opened, a flow of fuel moving from the pressurizing chamber and axially colliding with the valve body is radially distributed in the radial direction of the valve body to become a flow directly moving the discharge ports and a flow colliding with an inner wall of the valve body housing before moving toward the discharge ports and then in a circumferential direction of the valve body. The discharge valve (8) is provided with a liquid damper chamber defined between an outer circumference of the seat member (8a) and an outer circumference of the valve body (8d) and an inner circumference of the valve body housing (8d) to face the flow in the circumferential direction. The liquid damper chamber includes first, second and third tubular passages (503A, 503B, 503C).

    Abstract: An object of the present invention is to reduce the pressure loss in a relief valve employed for a high-pressure liquid supply pump. Disclosed is a high-pressure liquid supply pump for pressurizing a liquid and supplying the pressurized liquid from a low-pressure side to a high-pressure side. The pump includes a relief path which releases the pressurized liquid from the high-pressure side to the low-pressure side, and a relief valve which is positioned in the relief path and equipped with an intermediate chamber, a valve seat positioned toward the high-pressure side of the intermediate chamber, a ball valve that is attachable to and detachable from the valve seat, and a ball valve retainer for pressing the ball valve against the valve seat. The relief path is configured so that an inflow path to the intermediate chamber and an outflow path from the intermediate chamber both produce a restriction effect. The ball valve retainer has a pressure reception surface for receiving the pressure from the intermediate chamber. A first pressure reception area, which detaches the ball valve from the valve seat upon receipt of liquid pressure of the pressurized liquid from a high-pressure section when the relief valve closes, is smaller than a second pressure reception area, which lifts the ball valve and the ball valve retainer upon receipt of liquid pressure from the intermediate chamber.
