A faucet assembly including a faucet body having a spout, a base, and hot and cold water flow control valves. The base houses a thermostatic mixing cartridge that tempers hot and cold water and has passageways that place tempered water from the thermostatic mixing cartridge and a cold water passageway in selective fluid communication with the outlet of the spout. During use, mixed water from the thermostatic mixing cartridge is regulated by the hot water control valve, cold water is regulated by the cold water control valve, and both the mixed water and the cold water are further mixed at a juncture of the mixed water passageway and the cold water passageway prior to exiting the faucet assembly via the outlet of the spout.

A trim system for a fluid control valve that includes a first stem driver coupled to a first actuator of the valve, a cage coupled to the first stem driver, a first handle coupled to the cage, a second stem driver coupled to a second actuator of the valve, and a second handle coupled to the second stem driver. The first stem driver and the cage are configured to compensate for axial and angular misalignment between the first handle and the first actuator, and the second stem driver and the second handle are configured to compensate for axial and angular misalignment between the second handle and the second actuator. Rotation of the first handle is configured to rotate the first actuator through the first stem driver and the cage, and rotation of the second handle is configured to rotate the second actuator through the second stem driver.

The hot and cold water mixing valve device includes a hot and cold water mixing valve unit; a flow control valve unit; a valve device main body; a hot and cold water mixing valve housing; and a flow control valve housing; and wherein the valve device main body includes: a hot water passageway permitting communication between only the hot water inlet of the valve device main body and the hot water inlet of the hot and cold water mixing valve unit; and a cold water passageway permitting communication between only the cold water inlet of the valve device main body and the cold water inlet of the hot and cold water mixing valve unit are formed on the interior of the valve device main body.

Flow control devices for convector heaters are provided. Such devices may include a casing in the shape of a cylindrical tube having in a first portion thereof, facing in a mounted condition towards the intake conduit of a convector heater, a plurality of first openings and in a second portion thereof, facing in the mounted condition towards the opposite side of the intake conduit, a plurality of second openings, the casing being arranged to be mounted onto the ceiling (S) in such a manner that the first and second openings allow the inside of the casing to be placed into communication with a first space (A1) beneath the ceiling (S) and with a second space (A2) above the ceiling (S), respectively; a closure member in the shape of a cylindrical tube which is mounted within the casing and is axially slidable relative to the latter between a first position, in which it leaves the first openings open and closes the second openings, and a second position, in which it closes the first openings and leaves the second openings open; and actuation elements for controlling the axial sliding movement of the closure member relative to the casing between the first and second position.

The present invention is directed to methods and apparatus for tempering the temperature of a liquid in a fluid conducting system. More particularly, the invention relates to tempering the temperature of water supplied to a fixture from a water heater in a fluid conducting system.

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.

A water control valve has a valve casing, a valve seat, a fixed valve plate, a movable valve plate, a driving piece, a press structure and a pulling structure, wherein the valve seat is assembled on one end of the valve casing. The fixed valve plate, movable valve plate and driving piece are disposed in the valve casing. A flow channel for the fluid is formed among the valve seat, the fixed valve plate and the movable valve plate. The driving piece is in contact with the movable valve plate. The pulling structure has a first shaft lever and a swing piece. The press structure pulls the first shaft lever the move axially. The first shaft lever pulls the swing piece to rotate, so that the driving piece drives the movable valve plate to slide laterally, the handiness of flow control or the on/off of the flow channel is enhanced.

A single control mixer valve structure for taps and fittings comprising a fixed disk provided with an outlet port and two ports, respectively, one for the hot water and the other for the cold water that come from two inlet openings, formed in a base, mounted in which is the fixed disk on which a mobile disk mounted in a mobile-disk holder is able to slide; the mobile-disk holder and the mobile disk define a mixing opening, which is adapted to connect the inlet openings with an outlet opening, formed in the base, in a position corresponding to the outlet hole on the fixed disk, from which the mixed water flows out; sliding of the mobile disk on the fixed disk causes partial opening or complete closing of one or both of the ports of the fixed disk, thus adjusting the amount of hot water and cold water that passes from the inlet openings to the outlet opening for the mixed water; the mixer valve structure is characterised in that the mobile-disk holder has, on the side facing the fixed disk, a body that is closed or is provided with one or more cavities and is configured so as to reduce the useful area of passage of the mixing opening.

A mixing valve (10) includes a valve body (12) having a hot fluid inlet (14), a cold fluid inlet (16), a mixed fluid outlet (18), and a cavity (20) in the valve body (12) between the inlets (14, 16) and the outlet (18). Mixing valve (10) includes a liner (30, 130, 230, 430, 530, 630, 730, 830) positioned in valve body (12) and a valve member (40, 140, 240, 340, 440, 540, 640, 740, 840) movable therein between a first position restricting the flow of hot fluid and a second position. Liner (30, 130, 230, 430, 530, 630, 730, 830) includes a downstream valve seat (74, 174, 274, 474, 574, 674, 774) that, when engaged by valve member (40, 140, 240, 340, 440, 540, 640, 740, 840), restricts flow of hot fluid past valve member (40, 140, 240, 340, 440, 540, 640, 740, 840).
