Abstract:
A spray head for discharging water, comprising:a body having an inlet and at least one outlet, the body having walls which define a water flow path from the inlet to the outlet and including a main path and pause chamber; a valve seat formed in the pause chamber; a spool movably mounted in the pause chamber and actuatable between an open position and a closed position, the spool being pressure balanced so that actuation force is independent of water pressure; a face seal attached to the spool, the face seal being engageable with the valve seat when the spool is actuated to the closed position to block water flow through the water flow path; and first and second seals attached to the spool on opposite sides of the face seal, the first and second seals having substantially equal outer diameters to maintain pressure balancing of the spool.
