  • Publication number: 20060081805
    Abstract: In the treatment of water, an end piece is connected to a treatment cartridge housing and inserted into an appliance having bypass, inlet, and outlet valves. The end piece has an end piece wall from which an inlet fitting, outlet fitting, and protrusion extend. The inlet fittings, outlet fittings, protrusion, and cartridge housing each have a longitudinal axis. The inlet and outlet fittings have a cam surface for actuating the inlet and outlet valves, respectively. Further, the cam surfaces of the inlet and outlet fittings are angled and vectored in relation to their respective longitudinal axis. The protrusion is shaped for actuating the bypass valve.

  • Publication number: 20050178705
    Abstract: A shutoff may comprise an engine for moving from a first position to a second position, and a casing for containing the engine. The shutoff may also comprise a valve. The engine may comprise a highly water swellable material. The casing may comprise at least one flow port. The engine may expand from said first position to said second position after a predetermined amount of time when contacted with water. The flow port may become at least substantially blocked, directly or indirectly, by the engine when the engine is in said second position. The engine may be used in a water treatment cartridge, and/or may be used to indicate the life status of a water treatment cartridge.
