초록

A valve assembly for permitting relatively free flow in a first direction and for preventing flow in a second, opposite direction in a flow path includes a housing having first and second ports and defining a housing interior having an interior surface. A resilient flow regulator includes a pair of lips arranged in a converging relationship to define for the regulator an open end and a normally closed end. At the normally closed end, the lips are disposed adjacent each other to define a normally closed slit therebetween, and to define inner and outer sur...
