    摘要: A lubricating structure for an engine includes a crankcase for supporting a crankshaft formed from a pair of case halves coupled to each other along a mating plane extending along a plane perpendicular to an axial line of the crankshaft. An oil reservoir in a lower portion of the crankcase extends across the mating plane. A pump chamber of an oil pump is formed between the two case halves across the mating plane. Lubricant is drawn from the oil reservoir into the oil pump using a structure which can achieve reduction of the number of parts and improve the ease of assembly. The structure includes a path groove, which forms an oil suction path for interconnecting the oil pump and the oil reservoir, formed in at least one of the two case halves.

    摘要: A pump assembly, comprising a pump and housing having an inlet passage and an outlet passage. The pump includes inlet and outlet ports and opposing first and second drive inputs configured to be rotated together in a pumping direction to operate the pump. The pump can be installed in the housing in a first orientation, in which the first drive input is configured for being rotated by a drive source in a first external direction to operate the pump, and a second orientation, in which the second drive input is configured for being rotated by the drive source in a second external direction opposite of the first external direction to operate the pump. In both the first orientation and the second orientation, the inlet port is in fluid communication with the inlet passage and the outlet port is in fluid communication with the outlet passage.

    摘要: A lubrication structure for an internal combustion engine includes a crankcase, an oil pump, and a relief valve. The crankcase is configured by connecting an upper crankcase on a mating surface of a lower crankcase, and has an oil pan. The oil pump and the relief valve are installed in the lower crankcase. The oil pump sucks oil in the oil pan through a suction passage, and discharges the oil into a discharge passage. The relief valve performs a valve-opening operation according to pressure of oil in the discharge passage to return surplus oil in the discharge passage to the suction passage through a surplus passage. These passages are formed in the lower crankcase. A relief valve housing section housing the relief valve, and the surplus passage allowing the relief valve housing section and the suction passage to communicate with each other, are provided to communicate with the mating surface.
