Abstract: A manually-operated valve is provided in series with an electromagnetically-operated valve and the manually-operated valve is provided with a proximity detector connected to the electronic controller whereby a switch in the manually-operated valve, in one position of the single control lever therefor, corresponding to about 50% of maximum supply rate, is operated to activate the proximity sensor and enable the water flow to be controlled by an object within its detection range. Removal of the object, e.g. the hand of the user from the range, will shut off the water through the manually-operated valve. Outside the position of the lever at which the switch is operated, the proximity detector is ineffective and control is effected exclusively by swinging the lever.

Abstract: A valve assembly has a one-piece housing having lower, upper, and side sockets respectively defining lower, upper, and side openings. A stepped mounting sleeve has a downwardly directed shoulder bearing inwardly on an upper-opening shoulder, an upwardly directed shoulder, and a threaded lower end engage in a holder inside the housing. An insert mounted on the holder has a front face directed outward at the side opening, adapted to carry a valve cartridge, and provided with connections for fluid supply lines. A mounting rod extending through the insert and sleeve has an upper end at the upper socket and a lower portion extending out of the housing through the lower opening. A nut threaded on the upper rod end bears downward on the upwardly directed shoulder of the mounting sleeve. Mounting structure engaged with the rod lower portion outside the housing secures the housing down against a mounting surface.
Abstract: A valve system in which a magnetic valve is in series with a manually-operated valve and contact with the handle of the manually-operated valve initiates flow via the electronic controller whereas, upon loss of contact, a proximity detector controls the magnetic valve when an object, such as a user's hand, is in range. The manual contact is superordinate and proximity detection is subordinate and the proximity detector remains permanently switched on during the operating duration.
Abstract: A shower fixture has a base adapted to be fixed to a wall, connected to a pressurized-water supply, and having a pressurized water outlet. A pair of generally parallel and spaced tubes have inner ends pivotal about an inner horizontal axis on the base and outer ends. At least one of the tubes is internally connected at the base to the outlet so that pressurized water can flow from the supply through the base to the tube. An element joins together the two tubes for joint pivoting. A shower head mounted between the outer ends is pivotal on the tube about an outer horizontal axis and is connected internally at the outer axis to the one tube so that water from the one tube can flow into the head.
