  • Patent number: 7347169
    Abstract: In an engine having a generator mounted thereon, an oil passage is formed within the engine's crankcase to supply oil to an oil jet for cooling one or more pistons. In addition, oil is supplied to an oil jet for cooling the generator, using the oil passage in common with the oil supply for cooling the piston, without requiring a separate, dedicated oil passage for the generator. The cooling oil delivery structure is provided for cooling the generator which is located at one end of the crankshaft. The oil passage for cooling pistons, which includes an oil jet for cooling each respective piston by jetting oil to the piston, is arranged on an axis substantially parallel to the crankshaft. A generator-cooling oil jet is provided on the crankcase at a terminal end of, and in fluid communication with the oil passage for cooling the pistons.

  • Publication number: 20070107691
    Abstract: A relief valve includes a cylindrical valve housing attached to an engine body continuously with a relief passage and an outlet provided in an axially intermediate portion thereof. A valve body is slidably fitted to the valve housing so as to allow the relief passage to communicate with the outlet as an oil pressure in the relief passage becomes equal to and exceeds a predetermined oil pressure. A skirt includes an upper end portion fixed to the valve housing above the outlet for guiding oil discharged from the outlet downward. The relief valve exerts a reliable defoaming function in response to an increase in the oil discharged from the outlet and an increase in an ejection pressure thereof while avoiding an increase in the size of the skirt. An annular recessed portion is formed on an outer circumference of the intermediate portion of the valve housing below the outlet.
