A water stream stop valve for a sprinkler includes a tube body, an annular cover, multiple securing units, and a drainage body having a hole at the center thereof, is arranged above the tube body by multiple support plates. The water stream stop valve is incorporated in a pop-up sprinkler that includes a main body, an expansion pipe with a stop member arranged at top internal diameter thereof, a spray head, and the water stream stop valve arranged inside the expansion pipe and below the spray head. When the spray head falls off expansion pipe, the water stream stop valve will be pushed up to the top of the expansion pipe and stop at the stop member for avoiding the overflow of water while maintaining the spraying at the original area, and delivering a service indication stream.

A device for dispensing liquid onto a target area of a vehicle surface is described, and includes a mixing valve that is in communication with a pressurized fluidic supply system via a fluidic distribution system, and a controller. The mixing valve includes an outlet orifice that is disposed proximal to the target area, and the mixing valve includes first and second valve conduits that are fluidly connected to the outlet orifice via a mixing portion. The first valve conduit includes a first control valve, and the second valve conduit includes a second control valve. The fluidic distribution system includes a first fluidic conduit and a second fluidic conduit. The controller is operatively connected to the fluidic supply system, and the first and second control valves.

A composite nozzle comprises: a housing having formed at one side thereof a cleaning liquid inlet through which the cleaning liquid is introduced, an installation port communicating with the cleaning liquid inlet at the other side thereof, and an air inlet path communicating with an air inlet on the outer side of the installation port; an opening and closing valve installed so as to be slidably movable toward one side and the other side in the installation port formed in the housing; an elastic body such as a spring that slidably moves the opening and closing valve while elastically supporting the opening and closing valve; and a cap which sprays the cleaning liquid to the outside from the other end of the housing in which the opening and closing valve is installed so as to be slidably movable in one direction and the other direction of the installation port.

A shower jet outlet nozzle includes a hollow chamber (1), a lateral wall (2) delimiting the hollow chamber transversely to a nozzle longitudinal axis (D.sub.L), and a bottom (3) delimiting the hollow chamber in the direction of the nozzle longitudinal axis on an outlet side, which bottom is made of an elastic material and in which a jet outlet opening structure (4.sub.S) including one or a plurality of jet outlet openings (4) and having an open initial configuration, wherein the bottom is configured with the jet outlet opening structure thereof, under the effect of a shower fluid operating pressure in the hollow chamber, to deform in an elastically resilient manner and thereby to steadily increase an opening cross-section of the jet outlet opening structure with increasing shower fluid operating pressure within a normal operating pressure range. According to one aspect, the jet outlet opening structure (4.sub.S) is spaced apart from the lateral wall (2), and the bottom (3) on an inner side (3.sub.I) and/or on an outer side (3.sub.A) has a weakening pattern (5) with a lesser wall thickness as compared to an adjacent region of the bottom, wherein the weakening pattern is designed to deform in an elastically resilient manner under the effect of the fluid operating pressure in the hollow chamber (1).

The present disclosure relates to a showerhead including an upper cover, a lower cover, and a middle plate disposed between the upper cover and the lower cover. A bottom portion of the middle plate defines a first water cavity and a second water cavity that is independent from the first water cavity. The middle plate further defines a first water inlet channel in fluid communication with the first water cavity and a second water inlet channel in fluid communication with the second water cavity. The lower cover includes a first water outlet in fluid communication with the first water cavity and a second water outlet in fluid communication with the second water cavity. The second water inlet channel includes a plug that can open and/or close the second water inlet channel responsive to water pressure exerted on the plug within the showerhead.
