Definitions

  • the present invention relates to an engine lubricating device including an oil pump which is housed in a crankcase and discharges oil in response to the rotation of a crankshaft.
  • a pump housing of an oil pump is constituted by a crankcase and a cover attached to the crankcase.
  • components constituting the oil pump such as a rotor, also have to be incorporated in the crankcase. Therefore, such an oil pump is likely to be difficult to assemble and maintain.
  • the invention has been contemplated in order to overcome the foregoing problems of the related art, and provide an engine lubricating device in which an oil pump is assembled separately from a crankcase, and facilitates assembling and maintenance.
  • claim 1 defines an engine lubricating device wherein: an oil pump is housed in a crankcase and discharges oil in response to the rotation of a crankshaft; a holder for rotatably supporting the crankshaft is attached on a surface of the crankcase where the holder is attached; and a pump housing for the pump is constituted by the holder and a cover fastened to the holder.
  • the oil pump is assembled on the holder which is attached to the crankcase, i.e. the holder is attached to the crankcase with the oil pump assembled thereon.
  • This structure is effective in facilitating assembly and maintenance of the oil pump.
  • a discharge path is formed on the holder, communicates with a discharge port of the oil pump at a first end thereof and opens at a second end thereof on a surface of the holder attached to the crankcase; and a discharge side oil path is formed on the crankcase, opens on the surface of the crankcase at a first end thereof, communicates with the second end of the discharge path, and introduces oil to a cylinder head.
  • This structure enables the oil path to extend from the oil pump to the cylinder head simply by attaching the holder to the crankcase. In other words, the oil path can be formed easily.
  • the engine lubricating device of claim 1 further features the following: an oil intake side oil path is formed in the crankcase, communicates at a first end thereof with an oil filter, which is positioned under the crankcase and filters oil pumped up therefrom, and opens on the surface of the crankcase at a second end thereof; an intake path is formed on the holder, opens on the surface of the holder at a first end thereof for the purpose of communicating with the second end of the intake side oil path (117) and communicates with an intake port of the oil pump at the second end thereof. Therefore, the oil path extends from the bottom of the crankcase to the oil pump simply by attaching the holder to the crankcase, which further facilitates the formation of the oil path.
