ABSTRACT:
An anti-siphon spray head has a housing and a chamber within the housing. An inlet and a plurality of spray openings communicate with the chamber. There is a flexible sleeve positioned within the chamber which masks the inlet to form an anti-siphon closure therewith. A movable valve member positioned within the chamber and within the flexible sleeve controls the flow of water from the inlet to the spray openings. There are means on the valve member which are in sealing contact with the flexible sleeve when the valve member is in a closed position.
