A clawless synthetic jet actuator includes a cavity layer having an internal cavity for reception of a fluid volume and an orifice providing a fluid communication between the cavity and an external atmosphere; and an oscillatory membrane having a piezoelectric material adapted to deflect the oscillatory membrane in response to an electrical signal. The cavity has an opening in at least one planar surface of the cavity layer, and the cavity layer and the oscillatory membrane are joined by a high strength, low shear modulus adhesive material with the oscillatory membrane positioned adjacent to the planar surface having the cavity opening and adapted as an enclosing surface to said cavity opening. The oscillatory membrane is adapted to compress and expand a volume within the cavity, based on a deflection generated by the piezoelectric material, for generating a fluid flow between the cavity and the external atmosphere through the orifice.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

A device for directing high pressure fluid includes: a spindle having a rigid body defining a fluid passageway therein; a spindle mount configured to mount the spindle to a fluid source; and a fluid distributer coupled to the spindle and including a plurality of spaced-apart fluid dispensers formed therein that are each fluidly coupled to the fluid passageway and configured to dispense fluid outside the device.

Embodiments of showerheads for use in a process chamber are provided herein. In some embodiments, a showerhead includes a first spiral channel extending from a central region to a peripheral region of the showerhead; a second spiral channel extending from a central region to a peripheral region of the showerhead, wherein the second spiral channel is interleaved with the first spiral channel and fluidly independent from the first spiral channel; a plurality of first channels extending from the first spiral channel to a plurality of first gas distribution holes on a lower surface of the showerhead, wherein each first channel is a singular channel extending at an angle; and a plurality of second channels extending from the second spiral channel to a plurality of second gas distribution holes on the lower surface of the showerhead, wherein each second channel is a singular channel extending at an angle.

An additive manufacturing nozzles includes a header (41) extending in a width direction of the chamber and which is configured to be supplied with inert gas from the outside, and a nozzle body (43) connecting with the header (41) in the width direction and is configured to horizontally blow out the inert gas, which is supplied from the header, to a molding area. The nozzle body has a honeycomb part (52) which defines an inside of the nozzle body into flow channels through which the inert gas flows, a blowout part (55) disposed downstream of the honeycomb part and which is connected with the honeycomb part in the width direction. The inert gas passed through the plurality of flow channels is led from the honeycomb part to the blowout part, and a porous part (54), which has openings, is disposed between the honeycomb part and the blowout part.

A steam injection nozzle for controlling the flowrate of steam injected into a hydrocarbon containing reservoir comprises a passage extending between an inlet and an outlet, wherein the passage comprises a first, pressure dissipating section and a second, pressure recovery section.

A semiconductor process system includes a semiconductor process chamber having an interior volume. A pump extracts gases from the semiconductor process chamber via an outlet channel communicably coupled to the semiconductor process chamber. The system includes a plurality of fluid nozzles configured to prevent the backflow of particles from the outlet channel to interior volume by generating a fluid barrier within the outlet channel responsive to the pump ceasing to function.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

The invention relates to a metering valve (1) for controlling a gaseous medium, in particular hydrogen, comprising a valve housing (2), wherein an interior space (3) is formed in the valve housing (2). A reciprocating closing element (10) is arranged in the interior space (3), which interacts with a valve seat (37) for opening or closing at least one passage channel (25). Furthermore, the metering valve (1) comprises a nozzle (11), the at least one passage channel (25) being formed in the nozzle (11) and the passage channel (25) having a circular-cylindrical portion.
