ABSTRACT:
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 surfaces for the lips. The regulator further includes at least one side wall interconnecting the lips. The regulator is secured within the housing interior so that flow in the first direction is from the first port, through the open end, through the normally closed end, and to the second port. The housing interior defines a shape such that the regulator is secured therein by the securing means with the outer surface of each of the lips being substantially adjacent to the housing interior surface.
