Abstract
A valve is provided which includes a valve body having a passageway from an inlet end to an outlet end and a tapered annular valve seat intermediate the ends, a plastic poppet being provided with a disc portion and a tapered portion which can engage the valve seat, the tapered part being stepped to provide a deflectable outer edge portion, the poppet including three beams which extend toward the inlet end of the body and are bent outwardly to enter a groove in the valve body, thereby providing resilient means to bias the poppet to a closed position. The valve body includes a transverse wall adjacent the valve seat, the wall having openings for allowing flow through the passageway and also including an opening that receives a post projecting from the poppet toward the outlet end and beyond the wall for engagement by a mating connector to displace the poppet to its open position.
