Abstract (en)
[origin: WO9516136A1] A swinging rotary compressor comprising a cylinder (1) having therein a cylinder chamber (11), a roller (2) fitted in an eccentric shaft portion (31) of a driving shaft (3) and installed in the cylinder chamber (11), a blade (21) provided integrally with the roller (2) in such a manner as to protrude therefrom so as to divide the cylinder chamber (11) into a compression chamber (X) and a suction chamber (Y) and a supporting body (4) disposed in the cylinder (1) so as to freely swing therein and having a receiving groove (41) for receiving retractably the leading end of the blade (21), wherein an oil groove (22) is formed in the blade (21) and the axial end surfaces of a base portion of the roller (2) from which the blade protrudes in such a manner that the groove is open to the inner circumferential surface of the roller (2) at one end and to the protruding leading end of the blade (21) at the other end thereof, wherein a high pressure chamber (15) closed relative to the outside of the cylinder (1) is formed in the receiving groove (41) of the supporting body (4) on the back side of the blade (21), whereby sliding contact portions between the upper and lower end surfaces of the blade (21) and the roller (2), as well as between the blade (21) and the supporting body (4) for supporting the blade are positively lubricated to thereby improve the reliability.
