  • Patent number: 5833138
    Abstract: A cartridge (2) secured for angular movement on the handset head (10) has a valve-like cooperation with openings (12) in the head (10) for water flow via passageways (20, 21, 22) in the cartridge (2) to showering outlets (30, 31, 32) on appropriate rotational setting of the cartridge (2). Cleaning pins (7) rotatable with the cartridge (2) and co-axially movable relative to it are operated by a cam track (8, 81) to penetrate fine spray outlets (32) to clean them of scale. The cam co-action of the pin ring followers (71) with the track (8) causes the pins (7) to remain inoperative during the showering modes but the pins (7) are operated for penetration by further turning of the cartridge (2) i.e. independently of the showering modes. The followers (71) are spring urged against the track (8) such as by resilient blades (75) bearing against the taper periphery (27) of the cartridge (2). Clearance pin penetration of the outlets (32) permits water flow to wash away scale and minimize back pressure.
