Claims

[Scope of utility model registration request]

It is equipped with a reciprocating compressor that forms part of the refrigeration cycle, a bypass hole provided in the cylinder of this compressor, a control valve that opens and closes this bypass hole depending on the magnitude of back pressure, and an on-off valve. The control valve is equipped with a variable capacity circuit that applies back pressure to the control valve in accordance with the refrigeration capacity instruction of the compressor, and when the piston in the cylinder reaches the top dead center, the bottom dead center is removed from the bypass hole. An air conditioner characterized in that the piston ring is installed so that it is located on the dot side.
