The present invention provides a shower head system for the preservation of a water supply of a shower. The user is allowed the option to configure the water supply in a secondary outlet flow and a primary outlet flow. The secondary outlet flow, in some embodiments, is a droplet or rain-style flow. Without impeding the traditional or existing shower head the current invention allows the user to conserve water and customize different bathing experiences while doing so.

A switching device for shower system includes a housing; a valve core main body, wherein the valve core main body includes a first valve core and a second valve core, a first end of the first valve core is provided with a plurality of water passing holes in different positions, and a second end of the first valve core is slidably connected to the second valve core; a push rod, wherein the push rod is located inside the valve core main body, and an end of the push rod is inserted into the second valve core; and a switching assembly, wherein a first end of the switching assembly is slidably connected to the housing and a second end of the switching assembly is connected to the second valve core, when the switching assembly is pressed, the push rod is pushed to switch the water passing holes in different positions.

A top spray-water outlet device includes a top spray body, a switching device, clamping jaws, and elastic members. A water inlet, a shower water outlet and two top-spray water outlets are provided in the middle of an upper end of the top spray body. The water inlet is respectively connected to the shower water outlet and the top-spray water outlets. The switching device is arranged on one side above the top spray body. Upper and lower surfaces of the clamping jaw are respectively provided with a rotating shaft and a number of water outlet holes. The rotating shaft is rotatably fitted at the top-spray water outlet and is movably sealed. A water inlet hole is provided above the rotating shaft. The clamping jaws can function as a clamping mechanism to fix the hand shower and also as a water outlet device to spray water in this way.

A sprinkler head for attaching to a stem of a sprinkler, the sprinkler head having a round or polygonal shaped perimeter and comprising a directional nozzle array on the perimeter of the sprinkler head, the directional nozzle array comprises a single nozzle or a stack of nozzles each nozzle having an orifice facing a specific radial direction; the directional nozzle array being in fluid connection with a conduit through the stem for providing irrigation in the radial direction; wherein the directional nozzle array is provided with a dedicated regulator independently configurable by the user for regulating water flow in the specific radial direction over a range from zero when fully closed to a maximum range when fully open.

A spray gun shower head includes a shower body and a waterway closing element. The shower body is disposed with a first water passageway communicated with a water intake opening and a first water outflow opening (12), and a second water passageway communicated with the water intake opening and a second water outflow opening. The second water passageway is configured to spray the spray gun water. The waterway closing element is rotatable to a second switch position to open the second water passageway and close the first water passageway while driving an opening structure to push against a cover to be flipped up, so that the second water outflow opening hidden in the shower body by the cover sprays the spray gun water.

The invention relates to a fuel injector for internal combustion engines for injecting fuel at high pressure, comprising a pressure chamber formed in an injector body, in which pressure chamber a nozzle needle is arranged in a longitudinally movable manner, which nozzle needle has a cone region tapered in a combustion chamber direction and a pin region having a constant diameter d23 at a combustion-chamber end of the nozzle needle. The injector body has a substantially conical nozzle needle seat, from which a first injection opening extends, and a blind hole, which adjoins the nozzle needle seat on the combustion chamber side. The blind hole has a cylindrical segment, which has the diameter d31, and a hole base, from which a second injection opening extends. The cone region of the nozzle needle interacts with the nozzle needle seat and thereby opens and closes the first injection opening and the second injection opening with respect to the pressure chamber. During a partial stroke of the nozzle needle, the first injection opening and the second injection opening are connected to each other by means of a throttle gap, which is formed in the blind hole between the pin region and the wall of the blind hole, and the throttle gap remains constant at least over the partial stroke of the nozzle needle.

A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes a first outlet with one or more openings aligned along a first lateral section and a second outlet with one or more openings aligned along a second lateral section. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the first outlets along the first lateral section of the delivery tube to deliver the fluid out of the device in a first lateral direction, and a second axial position that aligns the second outlets along the second lateral section to deliver fluid out of the device in a second lateral direction.

A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and directs fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The assembly comprises a cylindrical poppet slidably disposed within the central bore, a guide between the nozzle body and the poppet, and a biasing member within the cartridge case between the front portion of the nozzle body and the poppet urging the poppet away from the front portion of the cartridge case.

A method and apparatus for providing a self-powered variable fountain display is disclosed. A high-pressure source of water is applied to a bifurcated manifold. A first portion of the manifold supplies a distribution chamber within which is a plurality of distribution holes, each of which is capable of driving an individual fountain display nozzle. A second portion of the manifold provides motive power to an impeller that in turn drives a gear system used to select which of the plurality of distribution holes is active.

A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes an outlet. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the outlets to deliver the fluid out of the device in a lateral direction and a second axial position that misaligns the outlets to impede the fluid from being delivered out of the device in the lateral direction.
