For to avoid clogging from abrasive media, a nozzle contains an element for circular vortexing the passing jet of detergents in combination with a defined flexibility of its elements, whichtogether with a pulsating stream of mediacauses vibrations, that constantly lead to peeling off adhering residues.

A nozzle arrangement that produces an atomised spray or foam wherein the nozzle arrangement comprises a nozzle body with an inlet for a pressurized fluid into a chamber with an outlet orifice in the downstream wall and a prodder with a tapered conical tip wherein the prodder is inside of said chamber and at least part of the tip of the prodder protrudes inside the outlet orifice creating at least one circumferential gap between the prodder tip and the outlet orifice whereby the fluid spins around at least part of the prodder tip and out through the circumferential gap and produces an atomized spray or foam with a substantially full cone shape.

A nozzle arrangement connected to a source of pressurized fluid mat produces a series of fast pulsed discharges of fluid in quick succession wherein the nozzle arrangement comprises a nozzle body with an inlet for the pressurized fluid into a chamber with a downstream wall with an outlet hole in said chamber wall wherein a prodder moves between a sealed and unsealed position in said outlet hole of the chamber wall and wherein a sprung plunger that is upstream of and connected to said prodder and has a annular seal that forms a seal between said plunger and the chamber creating a mobile chamber wall upstream of the downstream wall in said chamber, simultaneously moves between a downstream and an upstream position as the chamber fills with the fluid and then returns to a downstream position as the prodder returns from an unsealed position to a sealed position while the fluid is discharged.

A nozzle and methods of gas stripping utilizing the nozzle are provided. A nozzle is provided comprising a ceramic nozzle assembly comprising an inlet at one end of a cylindrical portion, an outlet at one end of a conical portion; the cylindrical portion transitioning to the conical portion at an end of the cylindrical portion distal from the inlet; the conical portion transitioning to the cylindrical portion at an end of the conical portion distal from the outlet; and a ceramic vane assembly within the cylindrical portion; the vane assembly comprising a central vane support located substantially concentrically within the cylindrical portion, and a plurality of angled vanes extending from the central vane support to an inner wall of the cylindrical portion; wherein the ceramic nozzle assembly and the ceramic vane assembly are manufactured such that the two assemblies comprise a single piece of ceramic.

The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.

Washing equipment for a vehicle includes at least one gantry defining a track for the vehicle, at least one nozzle supported by the gantry and intended to spray a cleaning liquid on the vehicle, and a helical profile that creates a helical rotational movement of the cleaning liquid relative to the gantry. The helical profile is suitable for ensuring the rotation of the cleaning liquid around the axis of the stream of cleaning liquid leaving the nozzle.

The invention relates to a device for rotating a fluid inside a spray nozzle, this device comprising a body defining at least one helical slot and/or a helical hole for the passage of all or part of the fluid. This device can be secured to a spray nozzle or a needle valve closing the spray nozzle. The invention also relates to an applicable device comprising such a device.

Provided is an apparatus for removing smoke and poisonous gas. The apparatus includes a body configured to include a flux unit which supplies water and a nozzle which is connected to the flux unit and has a narrower width than the flux unit, a frame configured to surround the body and include a suction part for removing smoke, and a heat sensitive unit fixed to seal the nozzle. When the flux unit, nozzle and frame sprays fluid with a certain pressure at high speed through the nozzle, pressure energy of the fluid is changed to velocity energy, and a vacuum state is formed in a suction room at a low pressure due to a fast speed. In order for an operation to be performed as a vacuum ejector for sucking another fluid, the suction part is positioned surrounding the nozzle, and the frame is provided to surround the heat sensitive unit. A negative pressure explained in Bernoulli's theorem is generated to form a vacuum in the space between the nozzle and the mixing chamber, thus enabling the suction of smoke and poisonous gas. The smoke and poisonous gas are mixed with water in the mixing chamber so as to be trapped in the water or dissolved and dispersed in the water. The suction part is formed in the area which encloses the nozzle such that the suction part can operate together with a vacuum ejector. The frame is arranged so as to enclose the heat sensitive unit.

The present invention is a spout apparatus (1) for spouting water, including: a spout apparatus main body (2) and an oscillation inducing element wherein the oscillation inducing element (4) has: a water supply conduit (10a), a water collision portion (14) disposed on the downstream end portion of the water supply passageway, for alternately generating oppositely circulating vortexes on that downstream side; a vortex street passageway (10b) for guiding vortexes formed by the water collision portion while causing them to grow; and a flow aligning pathway (10c) for aligning water including vortexes guided by the vortex street passageway, and causing it to be discharged; wherein a pair of opposing wall surfaces in the vortex street passageway is constituted so that the downstream side thereof is tapered over a longer area than the flow-aligning passageway, such that the flow path cross section thereof narrows toward the downstream side.

A spray pump is provided where two seal caps are arranged in an upper portion and a lower portion within a cylinder housing so as to prevent the contents from leaking, the cylinder housing a wall surface with one or more leakage discharge holes so that the content which can be accumulated within the cylinder housing is discharged through the leakage discharge holes rather than a content flow path, thereby enabling an efficient operation.
