Claims

[Claims for Utility Model Registration] 1. Annular bearings 74 and 75 are integrally fitted into a hollow cylindrical rotor 76, and an eccentric shaft portion 72 formed on the transmission shaft 71 via these bearings.
73 is supported in a rolling manner within the rotor 76, and as the transmission shaft 71 rotates, the maximum eccentric portion of the rotor 76 rolls into contact with the inner peripheral surface of the cylinder 40 within the compression chamber 44 of the cylindrical cylinder 40. and the partition plate 52 is telescopically extended from the inner peripheral surface of the cylinder 40 to the compression chamber 44,
A rotary compressor characterized in that the tip of the partition plate 52 is brought into contact with the outer peripheral surface of the rotor 76 to partition the compression chamber 44 into two chambers. 2. A convex portion 45 is provided on the main body of the cylinder 40 so as to protrude outward along the axial direction, a slot 42 is formed along the axial direction on the inner surface of the convex portion 45, and the slot 42 is provided with: 2. The rotary compressor according to claim 1, wherein said partition plate 52 is telescopically attached via a spring. 3 a suction casing 30 including a suction space 36; and a suction space 3 of the suction casing 30.
6, a discharge casing 60 having a discharge space 61 that communicates with the compression chamber 44 of the cylinder 40, an inner wall of the compression chamber 44, and the rotation of the transmission shaft 71. It has a hollow cylindrical rotor 76 whose outer wall surface at its maximum eccentricity is in close contact with each other, annular bearings 74 and 75 that are fitted and fixed in the cylindrical hollow part of the rotor 76, and eccentric shaft parts 72 and 73. Eccentric shaft portion 72
, 73, the transmission shaft 7 rotatably supports the rotor 76 via the bearings 74, 75.
1, and is inserted into the wall of the compression chamber 44 so as to be freely compressible,
2. The rotary compressor according to claim 1, further comprising a partition plate 52 which partitions the compression chamber 44 into two chambers by bringing its tip into contact with the outer wall of the rotor 76.
