    摘要: A pump includes a second housing member in which a suction-side groove and a discharge-side groove are formed at a predetermined interval in a circumferential direction of a bottom of a pump chamber so as to be recessed in the bottom of the pump chamber. Fitting portions that are fitted to bosses are formed on an outer surface of the second housing member. A protruding portion, which overlaps with the bosses in a thickness direction, is formed so as to protrude from a surface of the housing on which the fitting portions are formed. A relief valve is provided in the protruding portion, and the relief valve discharges fluid from the discharge-side groove when pressure in the discharge-side groove is equal to or higher than predetermined pressure.

    摘要: An oil supply system for an engine includes a pump body provided with a first outlet port and a second outlet port. The oil supply system further includes a hydraulic-oil-delivery passage, a first oil passage, a second oil passage and a return hydraulic passage. The valve body divides a hydraulic-oil receiving portion for receiving the hydraulic oil in the hydraulic-pressure control valve chamber into a first valve chamber and a second valve chamber. When the hydraulic pressure oil delivered to the hydraulic-oil-delivery passage is in a predetermined value, the hydraulic oil discharged out of the second outlet port is delivered to the hydraulic-oil-delivery passage via the first valve chamber. When the hydraulic pressure delivered to the hydraulic-oil-delivery passage exceeds the predetermined value, the hydraulic oil discharged out of the second outlet port is delivered to the hydraulic-oil-delivery passage via the second valve chamber.

    摘要: One example of a gerotor pump includes an inner rotor comprising multiple teeth, the inner rotor configured to rotate about a first longitudinal gerotor pump axis. The gerotor pump also includes a hollow outer rotor including an outer surface and an inner surface having substantially identical contours, the inner surface configured to engage with the multiple teeth and to rotate about a second longitudinal gerotor pump axis. The pump includes a pump housing within which the inner rotor and the outer rotor are disposed, wherein the outer surface of the outer rotor defines gaps between the pump housing and the outer rotor.

    摘要: An oil pump has a pump body, a pump cover, an outer rotor, and an inner rotor. The pump body includes a rotor chamber, a first inlet port, a first outlet port, a first inlet passage, a first outlet passage, a relief valve, a relief chamber formed on a discharge side of the relief valve, and a first oil return passage formed from the relief chamber to the first inlet passage. The pump cover has a second oil return passage. The first oil return passage is formed in an inner circumferential support wall of the rotor chamber as a groove-like recess and opens along an outer circumferential surface of the outer rotor. A support protrusion is formed near a portion where the second oil return passage is formed to support a front surface, in a radial direction, of the outer rotor.
