ABSTRACT:
A structure has individual oil passages for different applications of oil. A torque converter is provided on a crankshaft having an axially extending center hole. A crank chamber and a transmission chamber are separated from each other through a one-way valve. A pipe is inserted in the center hole of the crankshaft to form an oil passage for supplying hydraulic oil for driving the torque converter, an oil passage returned from the torque converter, and an oil passage for supplying a lubricating oil to the area surrounding the crankshaft. The oil passage returned from the torque converter is in communication with a chamber defined by a pair of inner and outer oil seals for sealing a bearing mounted on the crankshaft, a lower portion of the transmission chamber, and an oil passage having a check valve at the downstream end thereof.
