Abstract: Compressor is provided with an oil pump comprising an inclined passageway formed in the lower portion of a main shaft and inclined outward from below to above, a choke having a suction hole in the center that is smaller in cross section than the inclined passageway formed in the lower end of the main shaft, and a lower communicating section establishing communication between the lower end of a spiral groove and the inclined passageway, whereby the lift for the lubricating oil can be effectively increased.

Abstract: A sealed type electrically driven compressor that efficiently pumps up a necessary amount of lubricating oil even during low speed rotation and achieves good assembling workability by a simple construction. It is provided with an oil pump comprising an inclined passageway formed in the lower portion of a main shaft and inclined outward from below to above, a choke having a suction hole in the center that is smaller in cross section than the inclined passageway formed in the lower end of the main shaft, and a lower communicating section establishing communication between the lower end of a spiral groove and the inclined passageway, whereby the lift for the lubricating oil can be effectively increased.
