Abstract
A one way valve cartridge for a flow assembly includes a housing having an axial aperture formed therein. A leading ring is coupled to the housing. A piston is disposed in the housing and is in sliding relationship with the leading ring. The piston is configured to reciprocate between a closed position to seal the axial aperture and an open position to permit a flow of fluid through the axial aperture. A spring urges the piston into the closed position to seal with the housing.
