Claims

[Scope of utility model registration request]

A partition plate whose tip slides on the outer circumferential surface of the low link piston that slides on the inner circumferential surface of the cylindrical cylinder chamber to partition the suction chamber and the compression chamber is inserted into the groove provided in the cylinder so as to protrude and retract into the cylinder chamber. In the supported mouth-to-tally compressor, a concave groove extending in the axial direction is provided in at least one of the suction chamber side surface or the compression chamber side surface of the groove so as to open on both upper and lower surfaces of the cylinder; A rotary compressor characterized in that the concave groove communicates with a lubricating oil storage space formed below the cylinder via an oil supply passage.
