Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.

A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a twist-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.

The disclosure relates to faucet showers and discloses a seal switching mechanism including a seal switching mechanism, which includes a water shunt valve body, a valve shaft provided in an inner middle position of water shunt valve body and elastically connected with an inner bottom end of water shunt valve body, a valve body, a first water outlet channel, a first water outlet, a bubbler, a face cover, a spring, a gasket, a lower sealing port, an upper sealing port located above lower sealing port, a second water outlet, a second water outlet channel, and an assembly groove provided at a lower part of valve shaft. The upper and lower sealing port are arranged inside water shunt valve body, and gasket is installed inside assembly groove. The gasket adopts a special-shaped gasket with a step, which solves switching seal problem of switch sealing ports with different diameters on both sides.

A modular liquid distribution system in which each module has a module body, a spray nozzle, and a piston for controlling the dispensing of liquid from the nozzle. Each module has a pneumatically operated system for moving the piston to an open position while facilitating quicker return movement to a closed position, enabling the dispensing of precisely controlled small droplet sized quantities of highly viscous liquids.

A spray assembly includes an inner chamber, an outer chamber, a spray face, a plurality of shafts, a lever, a moving fulcrum, and a plurality of sleeves. The inner chamber provides a fluid in a first spray mode of a plurality of spray modes. The spray face is fluidly coupled to the outer chamber and includes one or more nozzles that are movable between a plurality of nozzle positions such that the spray face provides the fluid in a second spray mode and a third spray mode. The plurality of shafts are movable for directing the fluid within the spray assembly. The lever operates the plurality of shafts. The moving fulcrum changes a location of a fulcrum of the lever such that the fulcrum changes as the lever is operated. A first sleeve is configured to move the one or more nozzles of the spray face.

An anti-backflow device and a bidet are provided. The anti-backflow device includes a housing, an anti-siphon member, and a non-return assembly. A top of a water-passing chamber of the housing is provided with a vent. A bottom of the water-passing chamber is provided with a water inlet. A side wall of the water-passing chamber is provided with a water outlet. A sealing sheet of the anti-siphon member is movable to block the vent. The non-return assembly allows water to flow through the water inlet in only one direction.

A dosing valve is provided for ejecting a liquid from a nozzle outlet channel. The dosing valve has a main body, a valve actuating element movable within the main body, and a valve closure element connected to or actuatable by the valve actuating element. The valve closure element is movable within a dosing chamber between an open position, in which it is lifted off from a nozzle sealing seat, and a closed position, in which it lies against the nozzle sealing seat. For the pneumatic activation of the dosing valve, a switching valve is provided by means of which a working chamber of the dosing valve can be selectively ventilated or charged with a pressurized fluid.

A system and method to spray fluid from a container at different mass flow rates is provided. The system includes an actuator rotatable to select a mass flow rate and a valve having dual orifices that are selectively unsealed when the actuator is depressed according to the mass flow rate selection to effect dispensing of fluid.

The present disclosure relates generally to a showerhead with a pause assembly. The pause assembly can be partially received within a chamber of the housing and positioned between a fluid inlet and a plurality of nozzles to permit flow or substantially reduce flow from the fluid inlet to the plurality of nozzles. The pause assembly includes a valve and a lever coupled to the valve. The lever extends from the housing and movement of the lever in the first direction moves the valve to a first position to permit flow from the fluid inlet to the plurality of nozzles and movement of the lever in a second direction moves the valve to a second position to substantially reduce flow from the fluid inlet to the plurality of nozzles.
