Abstract

PURPOSE: To prevent generation of any clearance resulting in the internal short cycle of a pump by forming the pump so that its pump plate can be pressed down by means of a coil spring, in a compressor in which a displacement type pump for oil feeding is provided at the lower end of a drive shaft.
CONSTITUTION: In the titled compressor, a scroll type compressive mechanism 2 provided inside the upper portion of a closed container 1 is driven by an electric motor 3 positioned under it. A trochoid pump 10 is provided at the bottom end of a drive shaft 6 fixed to a rotor 3a of the electric motor 3, to suck lubricating oil from a lubricating oil pump 20 and supply it to each sliding part of the compressive mechanism 2. The pump 2 is composed of a pump plate 13, inner and outer rotors 14 and 15, etc., stored in a housing 11. In this case, a soil spring 21 is provided in a space B between the lower end of the drive shaft 6 and the upper surface of the pump plate 13, to press the pump plate downwards. Also, the spring 21 is so provided that its outer periphery may come in firm contact with the inner surface of the housing 11.
