Abstract
A gas check valve device having a header, at least one check valve plunger, at least one orifice that provides a first path for a small amount of gas to pass through the at least one check valve plunger when a respective compression spring presses the check valve plunger against a check valve seat to form an air tight seal, and a common gas passage connecting the check valve plunger with a common outlet. The gas check valve device provides a second path for a small amount of gas to pass through the orifice of the at least one check valve plunger in a reverse direction and a larger amount of the gas to pass between the at least one check valve plunger and the check valve seat when the gas pressure compresses the respective compression spring to separate the check valve plunger from the check valve seat.
