OSCILLATING TYPE ROTARY COMPRESSOR

Title:

OSCILLATING TYPE ROTARY COMPRESSOR

Document Type and Number:

WIPO Patent Application WO/1995/018310

Kind Code:

A1

Abstract:

A rotary compressor, wherein a roller (6) adapted to fit over an eccentric portion (51) of a driving shaft (5) is relatively rotatably installed in a cylinder chamber (21) of a cylinder (2), a blade (61) provided in such a manner as to integrally protrude from the roller (6) is oscillatably supported on a support (62) which is rotatably disposed in the cylinder (2). Then, an oil groove (64) opening to the axial end of the roller (6) is formed in the internal circumferential surface of the roller (6) and on a counter-loading side between the blade (61) protruding position and a position displaced 180 degrees from that position in the rotating direction of the driving shaft (5), and oil is positively supplied from this oil groove (64) to the sliding surface. Due to the configuration described as above, although it is an oscillating type rotary compressor in which the roller (6) performs relative rotations, the rotary compressor described above provides good lubricating conditions on the external circumferential surface of the eccentric portion (51) of the driving shaft (5) and the internal circumferential surface of the roller (6), whereby seizing wear are prevented, thereby improving reliability.
