ABSTRACT:
A shower head assembly having a flow regulator for maintaining a flow rate through the shower head within preset limits, substantially independent of variations in supply pressure and operating temperature. The flow regulator includes a flow controller element disposed in a regulating chamber, biased in one direction by a metallic spring and urged in the opposite direction by supply pressure. The controller element cooperates with an outlet passage in the regulating chamber to form a variable orifice, reducing the effective area of the outlet in response to increased supply pressure. A retainer screen keeps the flow controller and biasing spring in place while serving as a protective filter.
