Abstract: A mixer faucet having a left-right clicking mechanism and configured to increase a degree of freedom of the faucet is provided. The mixer faucet includes a lever handle and a valve assembly. The valve assembly includes: a tilting lever that is configured to move in conjunction with a movement of the lever handle, turn forward and rearward, and also turn leftward and rightward; a lower case; an upper case; a lower sealing member; an inner sealing member; and a click rotary member. The click rotary member is exposed to the outside of the valve assembly. The click rotary member is rotated leftward and rightward by a rotation force applied from the tilting lever. The click rotary member includes a first click engaging portion. The upper case includes a second click engaging portion. An engagement between the first click engaging portion and the second click engaging portion generates a left-right click.

Abstract: Disclosed is a high flow valve seat for a water control valve, including a main body, wherein the main body has one end and a circumferential part. The main body forms a waterway and several flow channels which straight extend from the end into the main body respectively. The main body forms several through holes connected to the flow channels respectively. The flow channel is formed of a first wall surface, a second wall surface and a third wall surface. The first wall surface is laterally adjacent to the circumferential part. The second wall surface and the third wall surface abut on both sides of the first wall surface respectively, and the second wall surface and the third wall surface extend away from the circumferential part respectively, so as to enlarge the cross-section area of the flow channel and to increase the flow of water to the valve core structure.

Abstract: A faucet that uses a gearing mechanism to allow the faucet handle to be placed much closer to the mixing valve is disclosed. Various embodiments involve geared mechanical operation of a mixing faucet, where the gears transfer motion of a handle to a faucet valve, which may allow for a lower handle (e.g., a handle placed closer to the faucet body). In some embodiments, an upper gear is provided in a faucet handle, and the upper gear may be held in a carrier. A set screw may lock the handle in place. Finally, a lower gear may be pushed onto the top of a valve stem. When the handle is lifted, the upper gear rotates against the lower gear, causing the valve to open. The carrier may rotate within the valve body, thus allowing for temperature control of the valve.

First and second inlet ports are arranged on one of said first or second end portions, and at least one outlet port is arranged on one of said first or second end portions.

Abstract: The present invention relates to a sanitary fitting having a fitting house and having a control cartridge which is arranged in the latter. The control cartridge has a control shank which is pivotably mounted in the control cartridge. On the control shank is displaceably mounted an actuating lever which can be pivoted up and down between a closed position and an open position in order thus to control the water flow. Furthermore, a plate is mounted at one end on the guide element and at the other end on an axis of rotation which is fixedly arranged with respect to the pivot axis and which is parallel thereto. By means of this arrangement, during the pivoting of the actuating lever from the closed position in the direction toward the open position, said actuating lever is also moved in the direction away from the control shank and, in the direction of the cartridge axis, away from the fitting housing.

Abstract: A ceramic control valve includes a valve casing, and a control device including a linking seat and a control lever. The drive block of the control lever has a spherical surface. The receiving hole of the linking seat has a wall having a first portion in contact with the spherical surface of the drive block and a second portion spaced from the spherical surface of the drive block, thereby forming a plurality of gaps. Thus, the gaps located between the drive block and the receiving hole keep a smooth circulation of the air flow, thereby preventing the drive block from being jammed in the receiving hole due to deformation of heat expansion, so that the control lever is operated normally.

Abstract: A mixer cartridge contains a plate-type control system, the control plate of which is displaceable and twistable by an actuating element configured as a double-armed lever. The displacement leads to an opening and closing of the valve, while the twisting serves to alter the temperature. According to the invention, it is envisioned that the maximum opening and closing position of a holding plate controlling the movable control plate is limited by stops. For the actuating element, a stop is also provided, which acts in the same way, yet is arranged such that it still has a minimum distance from the actuating element when the holding plate is already bearing against the stop.

Abstract: A single-lever mixing valve with stirrup-shaped handle (9) comprises a mixing cartridge (2) which is arranged in a fitting housing (1) and projects with an actuating shank (14), pivotable about a pivot axis (16), into a handle head (18) closed off to the outside, it being possible for the actuating shank (14) to be actuated by the stirrup-shaped handle (9) via pins (11, 11?) leading into the handle head (18). In such a single-lever mixing valve, increased hygiene and an improved visual impression are achieved in a simple construction by the pins (11, 11?) being rotatably mounted about a rotation axis (17) which is in alignment with the pivot axis (16) of the actuating shank (14).

Abstract: A valve core for a single handled faucet is made up of a valve housing, a valve stick, a base mount, a switching control valve, and a valve seat wherein the base mount, engaged with the valve stick and mounted onto the switching control valve thereof, is securely located at the valve housing therein, stably refrained from being moved or rotated by the valve stick thereof in operation. The valve stick is pivotally moved at the base mount therein to activate the switching control valve via a protruding connecting section thereof, driving an upper switch valve of the valve seat joined to the bottom of the switching control valve thereof to open the valve core for water discharge. Via a protruded guide spot of the base mount as a pivoting point, the valve stick is also rotated left or right with a turning protruded block thereof moved at a turning cut area of the base mount therein to adjust the water temperature.

Abstract: A fluid control valve for controlling the delivery of water includes a control lever that is movable in two directions by rotation of the lever about two independent axes. The fluid control valve includes a valve body assembly with flow passageways and a housing assembly attached to the valve body assembly to define an interior space. A flow control mechanism positioned in the interior space is constructed to enable movement of the lever about a first axis for translating rotational movement into sliding motion of an upper disk against a lower disk to adjust the water temperature. Rotation of the lever in a second direction translates rotational movement into sliding motion of the upper disk in a second direction to control the water flow rate. A drag spring positioned as part of the control mechanism changes the frictional force or feel between the two directions of lever movement.

Abstract: A faucet includes a main body, a control valve, a drive shaft, and a handle. The drive member of the drive shaft has a peripheral wall contacting with the mounting recess of the control seat of the control valve and formed with a plurality of spacing portions to reduce a contacting area between the drive member and the mounting recess to prevent the drive member from being expanded excessively due to absorbing the water to jam the mounting recess, so that the drive shaft is operated easily and conveniently, thereby facilitating the user operating the faucet.
