Claims

[Scope of utility model registration request]

, a rotating piston installed eccentrically in the cylinder,
A vane □ is in pressure contact with the rotating piston and divides the cylinder into the suction chamber and the compression chamber. In a rotary piston type compressor, the rotary piston type compressor includes a vane chamber which is housed in such a manner that the internal space is communicated with the suction port side which communicates with the suction chamber, and the inner surface of the vane entrance and exit of the vane chamber is the surface facing the compression chamber side. A seal insertion groove with a semicircular cross section and a length corresponding to the vane width is formed in the seal insertion groove, and a seal material with the same semicircular cross section as the groove is inserted into the seal insertion groove, and the seal material is inserted into the seal insertion groove side. A rotary piston type compressor characterized by being provided with a spring that presses the vane toward the vane.
