A fluid dispensing device and method for controlling the device are provided. The device includes a housing defining a fluid outlet. A valve controls the flow of fluid to the outlet. A sensor is configured to detect an object outside of and proximate to the housing. A solenoid is configured to move the valve between an open position and a closed position. A controller is configured to receive the output signal of the sensor, determine a characteristic of noise in the output signal such as a level of noise; adjust at least one of a sampling rate of the output signal and an amount of filtering of the output signal responsive to the characteristic of noise in the output signal, and transmit a control signal to the solenoid responsive to the output signal.

Methods and systems for the distribution, regulation and mixture of fluids, but particularly for the regulation of water flow through a tap, within a water distribution system, and for the regulation of the temperature of said flow from mixtures of smaller flows than the flow of the water distribution system, where at least one execution-by-the-user means is coupled, wherein the user has no contact with the mechanical parts of the system. Furthermore, systems for the reuse of water remaining in the pipelines, preventing waste and allowing remote activation, are revealed.

A bar valve includes an elongate housing having a first inlet located towards a first end of the housing, a second inlet located towards a second end of the housing, and an outlet located between the first inlet and the second inlet. A mixing chamber is located within the housing, the mixing chamber being configured to receive first and second input flows from the first inlet and second inlet, respectively. A flow controller is configured to receive a mixed flow from the mixing chamber and controllably output an outlet flow to the outlet. The mixing chamber and flow controller is disposed sequentially in a region of the housing between the first end and the outlet, thereby confining the mixed flow and the outlet flow to the region of the housing between the first end and the outlet.

An automatic faucet includes a faucet body, an inner tube, a faucet nozzle, a sensor, and a waterway control unit. The waterway control unit is fitted in the faucet body. The waterway control unit includes a mixed water valve core for delivering water to the inner tube, a solenoid valve for controlling water flowing out from the inner tube, and an integrated valve seat for accommodating the mixed water valve core and the solenoid valve. The sensor is electrically connected to the solenoid valve. The structure and the assembly process of the faucet are simplified.

A pair of levers are provided extending from a common junction to free tips which are spaced from each other. The junction is coupled to a valve of a faucet, with such a coupling either being direct or with intervening structures. The valve can be controlled by a user manual gripping and applying force to either the first lever or the second lever. The levers are sufficiently far apart that a user can control the valve while only touching one of the levers. The junction can be removably attachable to a control knob coupled to the valve or can be built into the faucet. The two levers are preferably elongate in form and preferably include indicia thereon indicating that one of the levers should be used first and the other of the levers should be used last. In one embodiment, the indicia include the wording “dirty” and “clean.”

A cartridge valve includes a housing, a stem adapter, and a stem assembly. The stem adapter includes a body defining a first hole, which extends in a longitudinal direction. The stem assembly includes a first stem component and a second stem component. The first stem component includes an arm and a spherical portion that is configured to be at least partially positioned within the first hole and defines an opening. The second stem component has a body that is configured to be at least partially received within the opening of the first stem component. The spherical portion is configured to expand in size in response to the first end inserting a portion of the body of the second stem component into the opening in the first stem component, which increases a frictional resistance induced by relative rotation between the stem assembly and the stem adapter.

A mixing cartridge (1) for a sanitary faucet, comprising at least: a mixing chamber (2) having at least one hot-water inlet (3) for hot water and at least one cold-water inlet (4) for cold water, and a vortex element (5) for at least partially swirling the hot water and the cold water in the mixing chamber (2), wherein the vortex element (5) comprises a plurality of outer wedge-shaped vortex bodies (6) and a plurality of inner wedge-shaped vortex bodies (7).

A fluid mixing assembly (100) comprising a body (102) having a discharge outlet (114) for discharging fluid; a fluid mixing device (104) disposed in the body (102) and in fluid communication with the discharge outlet (114), the fluid mixing device (104) having an adjusting member (122) adjustable about a mixing adjusting axis (124) and configured to assist in controlling mixing of fluids in the fluid mixing device (104); a first isolator (132) in fluid communication with the fluid mixing device (104) and configured to be coupled in fluid communication to a first source of fluid, the first isolator (132) having an adjusting member (140) adjustable about a first isolator adjusting axis (138) and configured to control a flow of fluid through the first isolator (132); and a second isolator (144) in fluid communication with the fluid mixing device (104) and configured to be coupled in fluid communication to a second source of fluid, the second isolator (144) having an adjusting member (152) adjustable about a second isolator adjusting axis (150) and configured to control a flow of fluid through the second isolator (152). The first isolator (132) and the second isolator (144) are disposed relative to the fluid mixing device (104) such that the mixing adjusting axis (124), the first isolator adjusting axis (138), and the second isolator adjusting axis (150) extend substantially in a common direction.

Device for a valve system, comprising: a housing with a seat for being coupled to a base and exchanging water streams when the housing is in a first coupling position, the seat comprising a first seat opening fluidly connecting to a first base opening when the housing is in the first coupling position; an adjuster which is contained inside the housing for adjusting the flow rate of one of the water streams; and a controller for controlling the adjuster. To avoid any complications in the event of an error while making the system more versatile, the seat comprises a breakable portion which can be broken off from the seat to enable it to be coupled in a second coupling position, the first seat opening subsequently fluidly connecting to a second base opening.

A set of universal switching modules is provided for mechanical touch faucets. The switching modules afford the same operational benefits and features as an electronic faucet without the necessity of resort to an electrical power supply, eliminating the need for electronic control circuitry, and simplifying installation while increasing long term operational reliability. The switching modules are activated by a linear depressing or a rocking motion that contrasts with rotary motions associated with rotating a valve stem. The switching module designs are agnostic to the faucet design meaning that the switching modules are universal in that the modules fit any faucet design. The switching modules work with a variety of activation methods used in faucet design illustratively including rocker switch concepts, push concepts, and a horizontal/perpendicular push concepts. Faucet manufacturers purchase a module based on the type of activation that they prefer for seamless integration in their faucet design.
