Abstract

The present invention relates to a variable capacity swash plate type compressor, in which a check valve for circulating refrigerant inside a compressor and preventing a backflow of the refrigerant when an air conditioner is turned off is mounted on a side of a discharge muffler chamber in a cover type so that the discharge muffler chamber is formed by the check valve, thereby reducing the number of components, the number of work processes, and a pulsating pressure (pulsating noise) of discharged refrigerant, allowing that the check valve is mounted at the center of a discharge chamber without any increase in size of the compressor, preventing an overlapping phenomenon of a pulsating pressure waveform of a high-pressure refrigerant at the time of discharge since the check valve is located at the center of the discharge chamber, and preventing a separation of the check valve by fixing the check valve in the discharge chamber via a retainer.

Description

technical field [0001] The present invention relates to a slanting plate type variable capacity compressor, and more particularly to such a slanting plate type variable capacity compressor, that is, a stopper for circulating refrigerant in the compressor and preventing the refrigerant from backflowing when the air conditioner is turned off. The return valve is installed in the form of a cover on one side of the discharge muffler chamber so that the discharge muffler chamber is formed by the check valve, thereby reducing the number of parts, the number of working procedures, and reducing the pulsating pressure of the discharged refrigerant (pulsation noise ), so that the check valve can be installed at the center of the discharge chamber without increasing the size of the compressor, thereby preventing the pulsation pressure waveform superposition phenomenon of the high-pressure refrigerant at the time of discharge due to the check valve being positioned at the center of the dis...
