OIL SUPPLY STRUCTURE OF DOUBLE ROLLER FOR COMPRESSOR

PURPOSE: An oil supply structure of a double roller is provided to attenuate a frictional resistance between an inner roller and an outer roller inserted into the outer circumference of a cam in a rotating shaft. CONSTITUTION: An oil supply structure of a double roller for a compressor comprises a rotating shaft(3), a cam(3a) and a cylinder(6). The rotating shaft is rotated with a rotor and the cam is formed in the lower portion of the rotating shaft. An eccentric portion is composed of an inner and an outer roller(5,5a) on the outer circumference of the cam and the cylinder holds the eccentric portion and connects a suction pipe. More than one oil guide groove(5b) is formed between the inner and the outer roller, vertically or curvedly penetrating through the entire inner circumference of the inner roller and the entire outer circumference of the outer roller. Thus, a frictional resistance between the inner and the outer roller is attenuated and a load applied to the rotating shaft is maximally reduced.
