Description
- N/A
- N/A
- The invention relates to an internal assembly for a faucet in which mixed water may discharge directly from the assembly.
- Single handle water faucets suitable for commercial and residential use are well-known. These faucets typically include, for example, a base plate, an upwardly extending main body portion, a discharge segment or spout, and a centrally located handle. A mixing valve or cartridge is positioned within the main body, and includes a vertically extending joystick that is operably connected to the handle. A hot water line or conduit is connected to a hot water inlet of the cartridge, and a cold water line or conduit is connected to a cold water inlet of the cartridge. The cartridge also includes a mixed water outlet, and a discharge line extends from the water outlet through the spout to provide mixed water for discharge. In operation, an operator actuates the handle to discharge water through the spout at a desired temperature and volume.
- Examples of single handle water faucets known in the art are described in U.S. Pat. Nos. 6,155,297, 4,337,795, 4,043,359, 3,965,935, 3,788,354, 3,035,612, 2,977,986, and U.S. Pub. Nos. 2007/0289648 and 2004/0074543. Mixing valve or cartridges known in the art are described in U.S. Pat. Nos. 5,957,160 and 4,979,539.
- Conventional single-handle water faucets suffer from a number of limitations that negatively affect their performance, durability and cost of manufacture. For example, some conventional water faucets locate the mixed water outlet in the rear portion of the cartridge. As a result, the discharge line in such faucets assumes an unnecessarily long and circuitous path to the spout that compromises durability and installation of the cartridge in the faucet body. Another disadvantage of conventional water faucets and mixing valves or cartridges is that water lines must be disconnected before the main body of the faucet may be removed for maintenance or replacement.
- The present invention is intended to solve these limitations and to provide advantages and aspects not provided by conventional faucet mixing valves or cartridges. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
- The present invention is directed to an internal assembly for a faucet having an independent base portion, a main body portion, a sealing element, at least one discharge element, a handle that an operator actuates to deliver water at a desired temperature through the discharge element, an annulus, and a radial seal.
- According to an aspect of the invention, the main body portion includes a lower disk with a cold water inlet, a hot water inlet, and a mixed water outlet; an intermediate disk with a recessed, arcuate mixing cavity, and a dual lobe sealing element positioned adjacent the lower disk; an upper disk with a central aperture positioned adjacent to the intermediate disk, with at least one engaging member that operably couples it to the intermediate disk; a seat with a central opening positioned adjacent to the upper disk; and a joystick, with a shaft extending through the seat opening and the main body.
- The joystick has a depending actuator that is received in the central aperture of the upper disk that operably connects it to the upper disk. Actuation of the joystick results in movement of the upper disk and intermediate disk, varying the position of the mixing cavity relative to the hot and cold water inlets.
- According to another aspect of the invention, the independent base is connected to a cold water line and a hot water line, and is mounted to a surface. The main body portion is secured to the independent base with screws, and is removable from the base without disconnecting the water lines.
- According to another aspect of the invention, the main body portion has cold and hot water inlet holes, and a mixed water outlet hole so that the mixed water may be discharged directly from the main body through a discharge element. The main body portion may include a change valve, which valve changes the flow of discharged water from one discharge element to another, such as between a spout and a water discharge line connected to the base portion of the assembly.
- According to another aspect of the invention, the radial seal is a U-ring, and the main body has an external, arcuate recess and two holes, all for receiving the U-ring.
