Methods and systems are provided for injecting fuel through three different rows of injector nozzles, where each row of the injector nozzle is arranged along a different vertical plane of the injector body. In one example, an injector needle housed movably inside the injector body may supply high-pressure fuel to each of the rows of injector nozzles sequentially to deliver up to five fuel injections in one actuation cycle of the fuel injector. In another example, a fuel injector may include three injector needles, where movement of each injector needle inside a respective chamber of the fuel injector body may supply high-pressure fuel to the chamber from where the fuel may be injected through the coupled fuel injector nozzles.

A handheld sink sprayer with single-handed metering and discharge mode adjustment. A body includes a handle portion, and a nozzle portion extending from the handle portion. A metering valve is carried in the body, a finger-engageable actuator is carried by the body and is coupled to the metering valve to move the metering valve, and a nozzle is carried by the body nozzle portion. A discharge mode valve is carried by the body nozzle portion. A thumb-engageable actuator is carried by the body nozzle portion and is coupled to the discharge mode valve to move the discharge mode valve between different discharge modes of operation.

A sprinkler system to control distribution of water flow to a plurality of sprinkler heads, the heads providing an outlet to dispense water passing through a corresponding one of the plurality of sprinkler heads and a plurality of distribution control devices, one of the plurality of distribution control devices coupled to a corresponding one of the plurality of sprinkler heads, wherein the distribution control device controls water flow to an associated sprinkler heads for a first predetermined period of time when a flow of water through the distribution control device is detected.

A shower system includes an inlet configured to receive water from a supply conduit and a plurality of spout outlets configured to discharge water from the shower system. A diverter is configured to receive water from the inlet and deliver water to the plurality of spout outlets, and the diverter is actuatable to change a water discharge mode of the plurality of spout outlets. A valve is configured to receive water from the inlet, and the valve is actuatable to a first position and a second position. A diverter actuator is configured to receive water from the valve in the second position. The diverter actuator is actuatable from an unactuated position to an actuated position upon receiving water from the valve, and the diverter actuator thereby actuates the diverter to change the water discharge mode of the plurality of spout outlets.

The present disclosure is related to a showerhead including a housing, a turbine, and a shutter. The housing defines a fluid inlet and a chamber in fluid communication with the fluid inlet. The chamber includes a plurality of engagement teeth and defines outlets for a first nozzle bank and a second nozzle bank. The turbine is received in the chamber. The shutter is received in the chamber and rotatably coupled to the turbine such that rotation of the turbine causes movement of the shutter. The shutter includes a plurality of shutter teeth positioned around a perimeter of the shutter. Engagement of the shutter teeth and the engagement teeth act to restrict the shutter from rotating while allowing the shutter to move across the chamber in a sliding motion.

The present application discloses a faucet head that controls pressure to lock its associated faucet into a fixed position. The basic structure may comprise an inlet, a faucet head body, an outlet and at least one internal water channel. The faucet head may adjust the faucet pressure to allow for the faucet head to become fixed in numerous positions, or to be used as a spray head. The faucet head would allow for a faucet acting in a flexible spray manner to become rigid and fixed in place at a user chosen position. The faucet head would also allow for the user to transform the faucet from fixed position to a flexible spray operation.

An improved showerhead assembly is provided for use with handheld showerheads. The handheld showerhead includes an elongate handle and a showerhead face including one or more nozzles for spraying water. In addition, the showerhead assembly includes a hollow mount for affixing to the male threaded pipe found in a shower stall. The mount includes a “C” shaped receptacle for holding the handheld shower assembly, an inlet for receiving water, as well as an outlet for expelling water to a flexible hose, which in turn is connected to the handheld showerhead. In addition, the mount includes supplemental spray assemblies which are affixed to the left side, right side or both sides of the “C” shaped receptacle. The supplemental spray assemblies can be rotated so as to expel water through different spray nozzle configurations.

A method of reducing water flow through a showerhead. The method may include dividing a water stream into two separate water groups and alternating the flow of water through the two separate water groups to reduce water flow through the showerhead.

The present disclosure discloses a shower head with a spray gun function and relates to the technical field of bathroom products. The shower head includes a shower head shell, the shower head shell, a surface cover water-outflowing body and a water distribution mechanism, and a hollow installing inner cavity is formed by the surface cover water-outflowing body and the shower head shell. By adopting the above technical solution, the present disclosure has functions of spray gun water outflowing and shower head water outflowing, water outflowing is switched by pressing a button, and thus the shower head is convenient to use and more suitable for meeting using demands of a consumer.

A nozzle unit for a reaction molding machine, comprising an inlet channel prepared for connection to a mixing head outlet and comprising a first dispensing nozzle, which is prepared for applying a reactive mixture and which is connected to the inlet channel in a first operating state, a second dispensing nozzle being present, which is connected to the inlet channel in a second operating state and which is likewise prepared for applying a reactive mixture. Further disclosed is a mixing head device for a reaction molding machine having the nozzle unit, to a reaction molding machine having the mixing head device, and to a method for producing a plastic part.
