Claims

[Scope of utility model registration request]

Bearing bodies are joined to both sides of the cylinder to constitute a compressor part, and a valve cover is provided on the outer surface of one of the bearing bodies, and the medium compressed in the cylinder is transferred to the valve cover. In a rotary compressor configured to discharge air to the outside of the compressor unit through a discharge passage formed in the compressor unit, the discharge passage is opened in the valve cover on the side surface of the bearing body on which the valve cover is disposed. A plurality of ports are provided to communicate with the outside of the compressor section, and a pulsation variation path consisting of a groove communicating with the outside of the compressor section is formed at the joint surface of the bearing body and the cylinder, and the pulsation variation path is communicated with the port. A rotary compressor characterized by:
