Claims

[Scope of utility model registration request]

(1) One end side of a slide vane that can freely reciprocate and is biased by a spring is brought into contact with the rotor, and the inner chamber of the compressor body, which is formed by the main cylinder and the frame plates on both end surfaces, is divided into a low pressure chamber and a high pressure chamber. In the rotary compressor, the refrigerant is sucked into the low pressure chamber from the first suction hole by the rotation of the rotor and is discharged from the first discharge hole of the high pressure chamber. and an auxiliary cylinder provided with a second discharge hole are provided in series, a piston that slides back and forth is provided in the auxiliary cylinder, and this piston is connected to the other end side of the slide vane to form a second compressor, This second compressor is connected to a cooling passage formed in the compressor main body, and the second compressor is connected to a cooling passage formed in the compressor main body.
A cooling device for a rotary compressor, characterized in that a refrigerant for cooling the compressor body is passed through the compressor.

(2) The cooling device for a rotary compressor according to claim 1, wherein the cooling passage is a groove formed at the joint between the main cylinder and the frame plates attached to both end faces of the main cylinder.
