<p>A compressor includes a compression mechanism (5) and a check valve (7) for preventing backward-flow of the gas in the suction path (3). The check valve (7) includes an accommodation hole (11) (its one end is opened toward the suction path and its another end is functioned as a reservoir), a valving element (13) movably accommodated within the accommodation hole (11), a valve seat (15) provided at the opened end of the accommodation hole (11) for closing the suction path (3) while the valving element (13) is pressed thereonto and an urging component (17) for urging the valving element toward the valve seat (15). A release groove (19) is grooved on an inner surface of the accommodation hole. The reservoir (9) is communicated with the suction path (3) through the release groove (19).</p> |
