Abstract (en)
A compressed gas is introduced from a compressor into an inlet 2aa of a check valve 1 and discharged through an outlet 3a from the check valve 1. A ball valve 5 is disposed on a valve receiver 6 between the inlet 2aa and the outlet 3a in the check valve 1. The ball valve 5 is more strongly pressed onto the valve receiver 6 in an upstream side than in a down-stream side to prevent back flow of the gas.
