Claims

[Scope of utility model registration request]

(1) A housing in which a compression chamber is formed on the inner circumference, a rolling member that is driven by an eccentric part of the drive mechanism and rolls along the inner peripheral wall of the housing, and an upper edge of the rolling member. Compression elements are arranged in series through the partition part, the compression elements being pressure-welded and having side edges in sliding contact with the partition member and dividing the compression chamber into a low-pressure chamber and a high-pressure chamber. A multi-cylinder rotary compressor comprising: a multi-cylinder rotary compressor, characterized in that the partition member is made of a heat-resistant, high-strength material, and its surface is processed to be smooth.

(2) Registration of a utility model characterized in that a protrusion is provided on one of the partitioning member and the division member, and a groove in which the protrusion is engaged is provided on the other member. A multi-cylinder rotary compressor according to claim 1.
