Abstract: A valve assembly (10) for permitting fluid flow in a first direction and for preventing fluid flow in a second direction opposite to the first direction. The valve assembly includes an upper housing (12), a lower housing (14) coupled to the upper housing to form a generally axially extending housing assembly, and a valve seating section (26) defined within an inner peripheral portion of the lower housing. The valve seating section includes an axially extending inner peripheral surface (38) and a transversely extending surface (44) substantially normal to the axially extending inner peripheral surface. A valve member (16) is seated within the valve seating section of said lower housing (14). The valve member (16) includes a flange (30) that extends from the valve member in a transverse direction and defines an axially oriented outer peripheral surface thereof (44). The valve member (16) is retained within the valve seating section (26) of the lower housing prior to assembly to the upper housing (12) by the axially extending inner peripheral surface (38) of the valve seating section (26) transversely compressing the axially oriented outer peripheral surface of the flange (30) to form a press-fit therebetween. Further, the valve member also includes a lower transverse surface (42) which is axially separated from the transversely extending surface of the valve seating section (44), in which an air space (40) is defined between these two transverse surfaces.
