Claims

[Claims for Utility Model Registration] 1. A rotary compressor comprising a condenser, a capillary tube, and a cooler connected in sequence to the rotary compressor, wherein a check valve is provided between the cooler and the rotary compressor. At the same time, first and second valve devices are provided between the rotary compressor and the condenser and between the condenser and the cooler, and the valve bodies of each of these valve devices are displaced in accordance with the suction side pressure of the rotary compressor. A refrigeration cycle characterized in that the rotary compressor is actuated by a pressure-responsive body, and each valve device is closed when the rotary compressor is stopped, and each valve device is opened when the rotary compressor is in operation. 2. A suction pressure chamber that communicates with the suction side of the rotary compressor, a first valve chamber that communicates with the discharge side of the rotary compressor and the outflow side of the condenser, and a first valve chamber that communicates with the outflow side of the condenser and the inflow side of the capillary tube. A valve case is provided integrally with a second valve chamber, and a check valve is provided at the inlet portion of the suction pressure chamber connected to the cooler side.
and each pressure responsive body of the second valve device is provided to separate the suction pressure chamber from the first and second valve chambers, respectively.Claim 1 of the Utility Model Register. Refrigeration cycle as described in.
