Abstract
A shower head that provides a series of spray effects. The shower head includes an inlet port to establish fluid communication with a source of water and at least two outlet ports to direct a spray with various effects to the user. A pushrod disposed in fluid communication between the inlet port and the outlet ports selectively opens the outlet ports to allow the user to continuously select any combination of spray effects, which may include a continuous stream or a pulsating jet. The pushrod is actuated by a rotating cam ring operated by the user. The cam moves the pushrod transversely across the inlet port and, under control of of the user, directs water from the inlet port to the outlet ports. The cam ring maintains the pushrod in the selected orientation.

A shower head providing a plurality of spray effects, comprising:
- inlet port means for establishing fluid communication with a source of water;
- first outlet port means for directing a spray of water with a first spray effect to a user of said shower head;
- second outlet port means for directing a spray of water with a second spray effect to said user;
- and
- pushrod means internally contained in said shower head and oriented generally perpendicular to the flow of water from said inlet port means, said pushrod means, disposed between said inlet port means and said first and second outlet port means, for selectively opening by rotary movement said first and second outlet port means to establish fluid communication with said inlet port means;
- and
- cam means, controlled by said user, for positioning said pushrod means to selectively open said first and said second outlet port means, whereby user can continuously select any combination of said first and second effects.
A method for generating a plurality of spray effects in a multi-function shower head having an inlet port and at least two outlet ports, with each of said ports providing a different spray effect, comprising:
- directing water through said inlet port;
- transversely moving a valve control rod which is completely enclosed within said shower head across said inlet port to selectively direct the flow of said water to one or more of said outlet ports;
- and
- controlling said transverse movement of said valve control rod with a cam surface operated by the user of said shower head.
