Abstract:
A nozzle for a fluid dispenser configured to dispense fluid includes a nozzle body and a valve stem that has a valve tip and is movable in an upstream direction and a downstream direction. The nozzle also includes an annular valve seat that is configured to contact the valve tip when the valve stem moves in the downstream direction, and a resilient annular portion that extends from the nozzle body and is adjacent to the annular valve seat. As the valve stem moves in the downstream direction, the resilient annular portion contacts the valve tip, flexes radially outwards, and thereby forms a sealing engagement with the valve tip, to avoid undesirable additional dispensed volumes that may be caused if the valve tip recoils away from the valve seat following initial contact of these elements.
