<p>The assembly includes a housing with a mounting flange, a cavity, and a skirt extending from the flange to the cavity. Water and air supply ports communicate with the cavity and a socket ring divides the cavity into water and air supply regions. A discharge ball assembly includes a ball pivotally received in the socket and a discharge nozzle. A bezel has a lip covering the mounting flange, a skirt covering the housing skirt and surrounding the discharge nozzle and an end portion retaining the ball in the socket. Water and air flows are controlled by a valve member within the ball, and an additional water path provides continuous flow to an ejector orifice leading to a mixing region where air is entrained in the water flow. The discharge nozzle rotates to control the valve member but does not move axially. A clamp member is drawn by fasteners against the tub surface opposite to the mounting flange, and the housing can be mounted in different positions. In each mounting position, drain paths in the socket, the housing skirt and the bezel lip are aligned at the lowermost part of the assembly to drain water from the assembly after use.</p> |
