Abstract

A check valve is provided, including a first hose connector housing defining an entry passage extending into an entry space at least partially defined by an annular valve seat, a second hose connector housing coupled with the first hose connector housing and defining an exit passage, and a generally flexible perforated membrane disk positioned between the first and second hose connector housings such that the membrane disk selectively engages the valve seat.
