An alignable conformal, cup-shaped flag-mushroom fluidic nozzle assembly is engineered to generate a flat fan or sheet oscillating spray of viscous fluid product 316. The nozzle assembly includes a cylindrical flag mushroom fluidic cup member 180 having a substantially closed distal end wall with a centrally located snout defined therein. The flag mushroom cup assembly effectively splits the operating features of the fluidic circuit between a lower or proximal portion formed in the housing's sealing post member and an upper, or distal portion formed in cup member 180 which, in cooperation with the sealing post's distal surface, defines an interaction chamber 192 fed by impinging jets each comprising a continuous distribution of streamlines that impinge at selected angles to define arcs providing a lesser degree of impingement at a centered axial plane within the exit orifice 194 and a greater degree of impingement at the edges of exit orifice 194.

Provided is a system and method for rapidly cleaning a surface utilizing a plurality of quick exhaust valves wherein the system is configured for particularly cleaning large or cylindrically shaped surfaces of sensors mounted to an exterior of a vehicle. The system and method contemplate the use of a plurality of quick exhaust valves arranged with at least one nozzle and at least one solenoid valve to efficiently express a dose of pressurized air onto the surface.

An outpouring assembly, comprising an outpouring plate, wherein the outpouring plate is provided with a liquid outlet through hole, a paste discharge pipe is disposed in the liquid outlet through hole, the paste discharge pipe moves up and down in the liquid outlet through hole, and when a lower end of the paste discharge pipe extends out of the liquid outlet through hole, the paste discharge pipe is in a liquid outpouring state. A beneficial effect of the present invention is as follows: Because a liquid such as the color paste or water has surface tension, the color paste adheres to a surface of an outlet, outpouring precision of the outpouring assembly is affected. A paste discharge pipe is disposed in the liquid outlet through hole, so that a quantity of color pastes adhered to a paste discharge outlet of the paste discharge pipe can be effectively reduced.

An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

A cleaning device for selectively bombarding a surface with a first medium, including an accumulator valve module having a high-pressure accumulator configured to store the first medium at a high-pressure accumulator pressure, an impulse nozzle configured to bombard the surface with the first medium, a changeover valve having a nozzle connector configured to connect to the impulse nozzle and a high-pressure accumulator connector configured to connect to the high-pressure accumulator, wherein the changeover valve is configured to: connect, in a release position, the high-pressure accumulator and the impulse nozzle via the high-pressure accumulator connector and the nozzle connector, interrupt, in a charge position, a flow path from the high-pressure accumulator to the impulse nozzle, and switch between the release position and the charge position. The cleaning device includes a high-pressure accumulator holding valve connecting the high-pressure accumulator to the first medium source.
