  • Patent number: 6363549
    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.

  • Patent number: 6085790
    Abstract: A faucet has a tubular faucet arm, a water-pressurizable hose in the arm having an outer end, and a head housing mounted on the hose outer end, extending along an axis, formed with a radially throughgoing slot, and dimensioned to be grasped in one hand. Body structure in the head communicates with the hose outer end and forms first and second valve seats and a nozzle assembly mounted on the body structure forms a first outlet communicating with the first valve seat and a second outlet communicating with the second valve seat. A valve element is displaceable in the body structure between a first end position engaging the first seat and diverting flow from the hose to the first outlet and a second end position engaging the second seat and diverting flow from the hose to the second outlet. A lever partially projecting through the slot from the housing is pivoted on the body structure.

  • Patent number: 6003170
    Abstract: A faucet assembly has a conduit defining a flow path between a supply of water and an outlet, a mechanical valve in the conduit and having an open position and a closed position, and a lever coupled to the mechanical valve for shifting it between its open and closed positions. A proximity detector has a detection field adjacent the outlet and a controller connected between the proximity detector and an openable and closable servo valve is activatable for opening the servo valve on detection of an object in the field of the proximity detector. A position-detecting switch associated with the mechanical valve is connected to the controller for activating this controller on shifting of the mechanical valve into its open position and for deactivating the controller on shifting of the mechanical valve into its closed position.

  • Patent number: 5992457
    Abstract: A valve assembly has a housing having an abutment and a valve cartridge in the housing having an actuating stem displaceable about a flow-control axis for varying a flow rate between a maximum flow and a minimum flow and about a temperature-control axis for varying temperature of the flow. A handle connected to the stem carries another abutment engageable with the housing abutment in a position of the valve cartridge corresponding to partial flow through the cartridge. A deflectable override button on the handle is operable to displace the handle abutment out of engagement with the housing abutment.

  • Patent number: 5421364
    Abstract: A flow-control valve has a valve housing and a valve element in the housing rotatable about an axis through at most 360.degree. between a fully open position for substantially unimpeded fluid flow through the housing and a fully closed position for substantially no fluid flow through the housing and through intermediate positions for intermediate levels of flow through the housing. A spindle coupled to the element extends along and is jointly pivotal with the element about the axis. A handle fixed on the spindle is provided offset from the axis with a handle stop so that the handle stop orbits about the axis as the handle and spindle are rotated to adjust the valve.

  • Patent number: 5213377
    Abstract: A fitting is formed with an outwardly open generally cylindrical bore centered on an axis and having an inner surface of a predetermined inner diameter. A tube end fits axially into the bore and is formed with a radially outwardly open groove, and a partial stiff sleeve of elastically deformable and strong material is engaged in the groove and has a frustoconically outwardly flared sharp outer edge of a predetermined outer diameter. Interengaging formations on the sleeve and on the tube end spread the sleeve and force the edge to bite into the inner surface of the bore on axial outward displacement of the sleeve and tube end. An elastomeric seal ring on the tube end offset from the groove radially outwardly engages the bore.

  • Patent number: 4989633
    Abstract: A wall-mount faucet assembly has a wall fitting adapted to be recessed in a wall and having an externally threaded stem projecting from the wall centered on an axis and formed with hot- and cold-water outlet ports. This fitting is formed with hot- and cold-water inlet ports behind the wall. A mixing faucet having an internally threaded collar engageable with the stem is rotatable thereon for axially displacing the faucet on the fitting. The faucet is formed in the collar with hot- and cold-water inlets connected in the fitting to the outlet ports. An adapter engaged in the collar between the faucet and the fitting has hot- and cold-water passages with upstream ends at the respective outlet ports and downstream ends at the respective inlets. The downstream ends are concentric such that the inlets connect thereto in any angular position of the faucet on the fitting.

  • Patent number: 4846207
    Abstract: The connecting fitting member for a cold and warm water mixing valve includes a coupler mounted in a structure wall, which has passages for two or more pipe connections and from which additional passages lead for connection of the mixing valve branch in a substantially transverse direction. The housing of the mixing valve has a base surface corresponding to the upper surface of the coupler. This connecting fitting member is improved, since a fitting member is inserted or mounted in the housing of the mixing valve, with which it is possible to reverse the connections for the cold and warm water by a rotation of 180.degree. and to fix the mixing valve in any angular position in the coupler.

  • Patent number: 4687025
    Abstract: A mixing valve has a base plate adapted to be fixedly mounted on a base fitting and a housing sleeve centered on an axis, mounted on the base plate for rotation about the axis, and formed with a radially open window. A stationary valve plate is fixed on the base plate inside the sleeve and formed with at least two incoming liquid ports and one outgoing water port spaced therefrom. A movable valve plate flatly sitting on the stationary plate inside the sleeve is formed with a chamber alignable with the ports therein. This movable plate is angularly and radially displaceable relative to the axis so the chamber variously overlaps and interconnects the ports. A control member fixed inside the sleeve to the movable valve plate is pivoted on the inner end of a control member also pivoted on the sleeve and having an outer end projecting radially from the sleeve through the window. The sleeve has a lower end rotatably mounted on the base plate and an internally threaded upper end.
