<p>A valve assembly (10) is disclosed for allowing fluid flow in a first direction and preventing fluid flow in a second direction. The valve assembly (10) includes a housing for enclosing a substantially circular regulator assembly (16) which extends diametrically across the housing. The regulator assembly (16) comprises a hub portion (24) which is positioned centrally within the housing and connecting members (26) which extend radially toward a rim portion (22) which is supported by the housing. The hub portion (24) supports a disk-shaped substantially inflexible portion of the regulator assembly (16) which extends over the connecting members (26) to engage the rim portion (22) and thereby prevent fluid flow in the second direction. The connecting members (26) of the regulator assembly (16) are adapted to flex and allow the disk portion (48) to move off of the rim and thereby allow fluid flow through the valve in the first direction.</p> |
