Abstract
PURPOSE: To compact the size and improve the cooling property in the titled power unit by a method wherein a motor and a pump are axially set in the containing space of the interior of a cylindrical tank in the power unit in which the motor and the pump are built in.
CONSTITUTION: The interior of a cylindrical tank 1 with a bottom consisting of an outside cylinder 6, an inside cylinder 7 and a bottom plate 8 is determined as a containing space 2, on the lower stage of which a totally-enclosed-fan cooled motor 3 is set and on the top of which a variable pump 4 is axially set on the space 2 respectively. Oil sucked through a suction duct 26 is discharged from a discharging pipe 30, and the oil is put back to the tank 1 via a returning pipe 27 and a drain pipe 28. Simultaneously, the air sucked from a notched window 9 in the lower part of the outside cylinder 6 is sent toward X direction due to a fan 3a driven by the motor 3 to cool the oil 5.
