Abstract
An evaporative control valve includes a plunger reciprocable between a valve stop and a valve seat to open and close a controlled port. The plunger has a body, a flexible support member mounted on one end of the body and a resilient tip positioned on the support member for sealing engagement with the valve seat. When the resilient tip of the plunger impacts the valve seat, the flexible support member absorbs substantially all of the force of impact by deflecting in the direction opposite the plunger movement, increasing impact time and reducing noise which may be generated. The resilient tip may be positioned on the flexible support member to further define a stop cushion to further reduce impact of the plunger against the valve stop.
