Abstract: The invention relates to a sanitary outflow fitting, especially a single-lever mixer (1), comprising, in a manner known per se, a housing (2) provided with at least one admission (5, 6) for water, and one outlet (49). A control cartridge (26) is located inside (10) the fitting housing (2), the manually operable control lever (34) of said cartridge controlling the flow of water through the outflow fitting (1). The aim of the invention is to be able to use a conventional control cartridge (26) with the admission and outflow openings thereof located on the lower side, even when the outflow (49) is in the upper or uppermost region of the outflow fitting (1). To this end, the control cartridge (26) is arranged inside a receiving insert (14). Water arriving towards the control cartridge (26) and leaving the same flows through said receiving insert (14).

Abstract: A water faucet includes a valve body, a valve seat, two water inlet pipes, a locking bolt, and a clamping member. Thus, the water faucet is mounted on the sink by the locking action between the clamping member, the locking bolt and the water inlet pipes, so that the water faucet is mounted on the sink easily and conveniently without having to mount the water faucet in a narrow space under the sink, thereby facilitating a user mounting the water faucet.

Abstract: A guide ring of a sanitary spout fitting having a swivelling spout which can be fitted swivellably on a fitting body via a swivelling sleeve which forms part of the swivelling spout, has material projections on both cylindrical faces. Through these material projections the guide ring is in contact both with the inner cylindrical surface of the swivelling sleeve and with the outer cylindrical surface of the fitting body. The guide ring thus ensures good radial guidance of the swivelling sleeve of the swivelling spout on the fitting body. Because the guide ring can rotate with respect both to the swivelling sleeve and to the fitting body in the new state, the smooth running of the swivelling spout is preserved even if one of these rotation possibilities is obstructed.

A hollow, cane-shaped spout mounts to the top end and seats a spray head at one end. A separate valve block mounts in the housing through the side opening and connects to a mixing valve cartridge lying adjacent thereto on a lateral side. Water supply hoses snap into inlet passages of the valve. One end of a counterweighted spray hose assembly snaps into an outlet passage of the valve block and the other end connects to the spray head. The spray head can be extended from the spout and then retracted. A method of assembling the hoses and valve assembly into the hollow faucet body through the side opening is also disclosed.

Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button.

Abstract: A self-contained unit 160 that rapidly and accurately senses, controls and maintains the temperature of water delivered to the user of a shower or bath. The invention allows a user to preset a desired water temperature using a manual control interface 60 and uses a sensor 10 located on (or within) the mixer outlet pipe 20 to measure the temperature of the mixed water being delivered to the user. The sensor produces an input signal that is used by a microprocessor 30 to calculate both derivative gain and proportional gain, and fuzzy logic may also be used by the microprocessor to produce an output signal, such that the system responds quickly and accurately to both quantum temperature changes and to the rate of temperature change. The output signal controls a motor 80, that via the action of gears 90, controls the action of the water mixer valve 110 thus maintaining a constant temperature of water delivered to the user.
