Abstract
PURPOSE: To make it possible to provide a common refrigerant passage and to simplify mechanism of a device, in the rotary compressor whose cylinder end plate is equipped with a gas injecting hole and a releasing hole, by providing in the refrigerant passage a check valve designed capable of opening and closing the releasing hole.
CONSTITUTION: In a section which is facing inside of a cylinder 22 of a bottom end plate 25, a gas injecting hole 34 and a releasing hole 35 are provided in such a manner as to penetrate a refrigerant passage 27 equipped with a check valve 33 designed capable of opening and closing a releasing hole 29, and further, these two holes are connected to a pipeline 36. It is possible, by using this mechanism, to conduct operation by constituting a gas injection refrigerating cycle by opening a 2-direction valve 15 and closing a 2-direction valve 16 and also by constituting a releasing circuit by closing the 2-direction valve 15 and opening the 2-direction valve 16. And therefore, it is possible to utilize a refrigerant passage in common, to reduce number of pipeline to be connected to the compressor and to simplify mechanism of the device.
