Abstract
A valve assembly is provided that includes a cup having a hub with an end wall and an opening therein. The valve assembly includes an annular seal interconnected to a cylindrical valve element by resilient radial ribs extending therebetween that provide for axial movement of the cylindrical valve element relative to the annular seal. The annular seal and cylindrical valve element are disposed within the hub with the top surface seated against the end wall in the hub. The cylindrical valve element is offset above the top surface such that when the annular seal is seated against the end wall the cylindrical valve element is axially displaced and compressed against the end wall to provide a minimum pre-load force effective for sealing off the opening. An actuator having a sleeve is disposed over the hub, and includes a plunger tip projecting eccentrically through the opening for unseating the cylindrical valve element.
