摘要： A variable oil pump includes a pump housing, a cover, an oil pump rotor rotationally driven while housed in a housing space between the pump housing and the cover, an adjustment member housed in the housing space to adjust the amount of oil discharged from the oil pump rotor by being displaced due to a drive force while rotatably holding the oil pump rotor from an outer peripheral side, and a guide portion including a groove in the adjustment member and a pin on the pump housing that engage one another. Engagement of the pin and the groove guides displacement of the adjustment member relative to the pump housing. A seal structure on at least one of the pump housing and the cover seals the inside of the groove relative to the housing space by surrounding a movement trajectory of the groove relative to the pin.

摘要： An oil pump is provided with an inner rotor having external teeth, an outer rotor disposed in a loose-fit state within a pump chamber and having internal teeth meshed with the external teeth, a ring-shaped pressure chamber provided adjacent to the pump chamber in a direction of a rotation axis, a discharge opening for connecting the pump chamber and the pressure chamber, and a cylindrical discharge passage having one end connected to the pressure chamber and the other end serving as a connection opening. A portion of the discharge passage is located to open inside of the outer periphery of the pressure chamber when viewed in the rotation axis direction. The one end reaches to a middle of the pressure chamber when viewed in a radial direction of the rotation axis, and the discharge passage and the pressure chamber are in direct communication with each other.

摘要： A diverter valve housing is secured to an upper end of a pump. A shuttle in the diverter valve housing moves between an upper closed position and a lower open position. A floating ring has an exterior band that abuts an upper end of the shuttle to move the shuttle downward. The floating ring moves upward when the pump operates. A bushing abuts an upward facing shoulder in the floating ring and is adhered within the bushing by a layer of adhesive. The shuttle has upper and lower seals separated by upper and lower spacer rings. A stop ring between the spacer rings limits downward movement of the upper spacer ring and also limits upward movement of the lower spacer ring.

摘要： An internal gear pump (100) comprises: a rotor/torque ring comprising an internally lobed (140) rotor (130) and a torque ring (120) extending beyond at least a first end (134) of the rotor; an externally lobed (160) idler (150) encircled by the rotor; a hollow shaft (190) supporting the idler; a pressure relief element (200) positioned to shift between a first condition and a second condition; and a spring (210) biasing the pressure relief element toward the first condition from the second condition. The torque ring has at least one pressure relief port (240A, 240B) positioned so that: in the first condition, the pressure relief element blocks a path from an interior volume (235) of the pump to the pressure relief port; and in the second condition, relative to the first condition the pressure relief element does not block the path.

摘要： A pump system includes a motor, a pump, and a single shaft extending from the motor into the pump, the single shaft being configured to operate simultaneously as both a motor output shaft and a pump input shaft. A first end of the single shaft interacts with the motor, and a second end of the single shaft interacts with the pump, to configure the shaft to operate as the motor output shaft and the pump input shaft. The pump system further may include a mounting accessory configured to support the motor and the pump. The motor may be an electric motor, and the pump may be a hydraulic pump. A drive controller is configured to generate commands for controlling the electric motor, which in turn drives the pump to achieve a desired flow of hydraulic fluid.
