<p>The valve assembly of the present invention includes a body portion having one or more inlets and two aligned outlets. The outlets are located on opposing faces of the body portion, one having a generally rigid valve seat defining a first valve outlet port and the other having a generally flexible valve seat defining a second valve outlet port. The valve assembly also employs a valve support assembly configured to move relative to the body portion generally along the axis of the aligned outlets. The support assembly has a flexible valve member at one end positioned inside the body portion and configured to engage the rigid valve seat to block flow through the first valve outlet port. The support assembly also has a generally rigid valve member positioned outside the body portion and configured to engage the flexible valve seat to block flow through the second valve outlet port. With this construction, when the valve support member is in an open position, both the flexible and rigid valve members are spaced from the rigid valve seat and flexible valve seat, respectively, allowing flow of fluid through the valve. However, when the valve support assembly is moved to the closed position, both the valve members are in contact with their respective valve seats and fluid flow is blocked.</p> |
