Abstract: An spray head includes a spray engine and a metal shell retained on the spray engine. The spray head is assembled by fitting the shell onto the spray engine and seating the shell against a cushioning ring. A retaining device is attached to the spray engine to secure the shell is position. A surface finish is applied to the outer surface of the shell to achieve a desired appearance.

Abstract: An adjustable metering actuator assembly for controlling the operation of a flush valve of a pressurized water closet includes a plunger assembly including a plunger carrying a tapered needle valve pin that is axially movable relative to an inlet orifice, the closing speed of the flush valve controlled by the fluid flow rate through the inlet orifice and the needle valve pin axially repositionable with respect to the plunger to change the diametral clearance between the tapered portion of the needle valve pin and the inlet orifice, thereby adjusting the fluid flow rate through the inlet orifice and thus, the bowl refill volume of the pressurized water closet.
