ABSTRACT:
A spray head assembly (10) includes a motion transmitter (71) in a spray-head compartment (20) coupled between an actuator shaft (45) and a relatively-rigid valve shaft (100') for transmission of motion from the actuator shaft into axial motion of the valve shaft to thereby move a relatively-resilient poppet member (76'), against liquid flow, away from a valve seat surface (80) when the actuator shaft is moved. The valve shaft which is located in a valve-seat passageway (78) downstream of the poppet member, includes a relatively rigid separate flange (102) thereon extending radially outwardly from the valve shaft. The flange has a bearing face (116) for impinging on a sealing face (114) of the poppet member directed substantially toward the valve seat. The flange fits in a raised ring seal (77') on the sealing face and extends into the valve-seat passageway when the poppet member is seated to be closed. The flange has a tapered outer/upper edge (112).
