PURPOSE:To eliminate the lack of supply of oil to a suction port of a forcible oil supplier, by providing an oil reservoir communicating a motor chamber to a crank chamber and guiding oil to the suction port of the forcible oil supplier. CONSTITUTION:Returned oil to a motor chamber is not returned to a crank chamber at a higher pressure but dropped by a head to be accumulated in an oil reservoir tank 12 provided to the bottom face of a bottom wall 1a in the motor chamber 1, and the oil is guided to a suction port 5 of a forcible oil supplier, in consequence the returned oil can be guided to the suction port 5 of the forcible oil supplier in no relation to a difference between pressures in the crank chamber 2 and the motor chamber 1, and a discontinuation of oil film, seizure and abnormal wearing of a bearing 3a can be prevented. |
