Abstract

PURPOSE: To introduce a great deal of external fluid at a time when vacuum is destroyed, by setting a suction passage for communicating a valve chamber with outside and also a check valve for inhibiting outflow from the valve chamber to outside.
CONSTITUTION: A suction passage 10 for communicating a valve chamber 6 with an outlet 5 is formed concentric with a small diameter around a position where a valve seat 7 is fitted, the end of the seat 7 facing the valve chamber 6 being formed as a check valve 11 made of disc film conical toward the chamber 6 and having an outer diameter larger than the concentric circle where the suction passage 10 is positioned. As the pressure in the valve chamber 6 drops below the outside level, the check valve 11 is bent downward to introduce a great deal of outside gas at a stroke through the suction passage 10. This construction can prevent damage of piping and devices used.
