发明名称 Valve assembly having articulating rigid seating surface
摘要 A valve assembly (10) including a valve body (16) having an orifice (52), and a valve member (20) received in the valve body and movable along an axis (A) with respect to the orifice. The valve member includes a cup (24) in an end (22) of the valve member and the cup has an end wall (25) facing the orifice of the valve body. A fulcrum (28) extends from the end wall of the cup towards the orifice, and a plug (30) is received in the cup against the fulcrum and opposite the orifice of the valve body. When the valve member is moved along the axis towards the orifice, the plug contacts the valve body to seal the orifice. The valve assembly (10) also includes a flat spring (32) having an outer portion (34) secured to the end of the valve member and flexible arms (36) retaining the plug in the cup, so that the plug can be articulated about the fulcrum and properly aligned with the valve body to fully seal the orifice when the valve member is moved along the axis towards the orifice.
