Claims

[Scope of utility model registration request]

An electric element and a compression element housed in an airtight container, this compression element consists of a plurality of cylinders arranged vertically in parallel through a partition plate, upper and lower bearings that close off the upper and lower sides of these cylinders, and the electric element described above. A cylinder deactivation control mechanism is provided in the middle of at least one of the suction pipes, which are each independently connected to the above-mentioned cylinders and are connected to the cylinders and which lead the refrigerant gas. In a multi-cylinder rotary compressor equipped with a cylinder deactivation control mechanism, a slider for opening and closing the suction pipe is provided in the housing of the cylinder deactivation control mechanism, and a sealing ring is inserted into an annular groove provided on the outer periphery of the slider to connect the sealing ring and the inside of the housing. A multi-cylinder rotary compressor characterized by close contact between the circumferences.
