A backflow preventing apparatus for a scroll compressor is disclosed, in which a check valve is hinge-coupled to a valve seat, or is coupled to a valve seat so as to be elastically opened and closed. The check valve is opened and closed by a pressure difference and its own weight or elasticity, thereby having a quick response speed. The check valve prevents discharged refrigerant from backflowing, thus enhancing efficiency of the compressor. Further, since the check valve when opened is prevented from colliding with a valve housing by a valve stopping su...
What is claimed is: 1. A backflow preventing apparatus for a compressor, comprising: a valve housing configured to be disposed between an inner space of a casing of the compressor and a discharge pipe that communicates with the inner space; a valve seat disposed in the valve housing and having a refrigerant passing hole through which the inner space of the casing and the discharge pipe communicate with each other; and a check valve rotatably coupled to the valve seat and configured to open and close the refrigerant passing hole of the valve seat, wherei...
