Claims

[Claims for Utility Model Registration] (1) A cylinder block formed in a hollow cylindrical shape in a housing, and a pair of front and rear side plates that shield both the front and rear openings of the cylinder block are built in, and A compression chamber is provided to allow the rotor to rotate freely, a discharge chamber is provided between the cylinder block and the housing, communicating with the end of the compression chamber, and an oil reservoir is provided at the bottom between the housing and one side plate. In a rotary compressor, an oil separation chamber is provided, and the discharge chamber and the separation chamber are communicated with each other via a discharge passage opened in one of the side plates. The opening side is provided so as to face the upper part of the separation chamber, and the opening side is provided so as to extend from the upper edge of the opening to the separation chamber on one of the side plates, and the opening side is provided so as to cover the upper and front sides of the opening. An oil separation mechanism in a rotary compressor comprising a first shielding plate formed in an inverted L-shape, and a second shielding plate extending horizontally so as to cover an oil pool in the separation chamber. (2) The rotary compressor according to claim 1, wherein the second shielding plate is formed into a gentle mountain shape with a downward slope in both the left and right width directions of the separation chamber. Oil separation mechanism in.
