The passage-switching valve according to the present invention has a stator and a rotor which is rotatable while sliding relative to the stator. The stator has a plurality of ports whose ends are open on a sliding surface on which the rotor is made to rotate and slide. The rotor has a passage groove for connecting two or more of the ports. At an edge of the passage groove, the rotor is in contact with the sliding surface of the stator at a contact angle a greater than 120°.

    Abstract: A ceramic control valve has a valve shell that orderly has a water control unit, an upper ceramic piece, a lower ceramic piece and a valve base connected underneath to avoid the abovementioned components from falling out. The ceramic control valve can change the water output style of the faucet without an additional handle, and the water output can be switched between front and top portions to effectively reduce the components of the faucets and simplify the assembly process.

  • Patent number: 8887764
    Abstract: A faucet comprises a spout, and a valve assembly that can be positioned in at least three different positions so as to draw water from a cold water reservoir, a hot water reservoir and lukewarm water reservoir. The valve assembly may comprise three valves, one valve for opening and closing the flow of water between each valve and the reservoirs. The lukewarm water reservoir receives water from the cold water reservoir which sits therein and raises up to room temperature. At least one handle provides for controlling the valves of the faucet so as to draw water from each reservoir or simultaneously from at least two reservoirs. A plumbing system including the faucet, conduits for each reservoir and a lukewarm water reservoir is also provided.

  • Patent number: 8844560
    Abstract: The most strained component of a cartridge is the bush, in which the control lever is mounted, using which the control can is moved. Upon actuation of the control lever to open and close the intakes and drains, the bush and thus also the extension of the housing and the front wall thereof are strained by bending. Upon mixing of the cold and hot water streams, friction forces arise in directions, which are perpendicular to one another, between the bush and the front wall of the housing and in the extension of the housing by rotation of the bush. All of these strains can result in hysteresis in the mixing position and in the position of the control cam during the opening and closing movements because of tolerances and play the opening and closing movements because of tolerances and play between the individual components. To overcome the strain issues, the bush bus has the control lever mounted therein is mounted using a conical face and also conical part of the front wall of the cylindrical housing.

  • Patent number: 8739338
    Abstract: An attachment apparatus (20) for attachment to the air conduits (6,8,10,12) of a zoned air cell cushion A or mattress to an associated valve. The attachment apparatus comprises a connector assembly (24) with connectors (26, 28, 30, 32) secured in the ends (N1, N2, N3, N4) of air conduits secured in a conduit constraint (38). Each air conduit is in fluid communication with a separate inflation zone (r,s,t,u) of the cushion or mattress. The connectors are in fluid cooperation with a valve (60) that places normally isolated zones into fluid communication and vice versa. The connector assembly may function as a base for any one of a number of valves (60, 103, 150, 200, 400, 500).

  • Patent number: 8695634
    Abstract: Provided are a sliding component, such as a mechanical seal ring, which is capable of maintaining superior sliding characteristics even in the long-term continuous use thereof, as well as a mechanical seal, a faucet valve, and a rolling support device, each of which includes the sliding component. The sliding component includes a stationary member, and a movable member contactedly sliding on the stationary member. The stationary member and the movable member are respectively composed of a silicon carbide sintered body containing graphite. The content of the graphite in one of the stationary member and the movable member is at least 4% by mass greater than in the other. Thus, the sliding component includes the stationary member and the movable member which are a combination of those having different contents of graphite. Owing to a high lubricating effect, the superior sliding characteristics can be maintained, permitting a long-term continuous sliding.
