Abstract

PURPOSE:To enable to feed oil at a constant rate, by providing inside an oil pipe with a coil spring made of a wire having a non-circular cross section which is arranged to turn together with a crank shaft, and feeding oil along a spiral passage. CONSTITUTION:When a rotor 3b is set into rotation by feeding current to an electric motor section 3, a crank shaft 6 begins to turn, so that a coolant gas drawn into a compression chamber 11 from a suction pipe 18 is compressed through rotation of a rotary piston 8. Along with rotation of the crank shaft 6, a space defined between the outer surface of a coil spring 15 made of a wire having a non-circular cross section and the inner wall surface of an oil pipe 13b is shifted upward successively along the lead of the coil spring 15 in a spiral manner, as shown by a, a', a'' in the drawing, and finally, it reaches a hydraulic chamber 16. Therefore, it is enabled to feed oil in a stable manner.
