Abstract
The check valve is used to control the flow of fluid through a cylindrical passageway having a cylindrical wall surface and comprises an elongate umbrella valve member having a frusto-conical shaped skirt extending radially outwardly and axially of the valve member. The skirt is positioned to extend in the downstream direction of the flow of fluid through the passageway and in frictional, sealing engagement with the cylindrical wall surface of the passageway but yet being flexible enough to deflect inwardly under fluid pressure to allow fluid to flow downstream past the skirt.
