A fluidic oscillator array includes a plurality of fluidic-oscillator main flow channels. Each main flow channel has an inlet and an outlet. Each main flow channel has first and second control ports disposed at opposing sides thereof, and has a first and a second feedback ports disposed at opposing sides thereof. The feedback ports are located downstream of the control ports with respect to a direction of a fluid flow through the main flow channel. The system also includes a first fluid accumulator in fluid communication with each first control port and each first feedback port, and a second fluid accumulator in fluid communication with each second control port and each second feedback port.

A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

An oscillating spray nozzle and related methods for providing spray patterns in a variety of oscillating patterns by driving movement of the nozzle with a progressing cavity displacement motor. By varying the design of the progressing cavity displacement motor, a variety of spray pattern geometries can be generated and a speed of the nozzle as it travels through the spray pattern geometries can be controlled. The oscillating spray nozzle can include a housing enclosing a progressing cavity motor that is operably connected to a spray nozzle. The progressing cavity motor includes a rotor member that is caused to rotate and oscillate within a stator member. The rotor member is operably linked to the spray nozzle, whereby the movement of the rotor member is communicated to the spray nozzle.

A fluid injector for x-ray tubes and a method to provide a liquid anode by liquid metal injection, wherein the fluid injector includes a device to inject fluid from an opening in a chamber of the device as a fluid jet generated by an arrangement to change the volume within the chamber, and includes a reservoir to store the anode material, which is fluidically connected by a pipe with the chamber of the device, where the pipe has a part formed in the fluid flow direction that is shaped to block fluid flow from the chamber to the reservoir during injection, and where the includes injecting fluid in a direction towards an electron beam and refilling the chamber with liquid metal from the reservoir.

A conformal, cup-shaped fluidic oscillator spray nozzle member (100, 200, 300, 400, 500) is configured to generate one or more oscillating sprays from fluid flowing into a substantially open proximal end and distally into a substantially closed distal end wall with one or more centrally located orifices defined therein. A multi-input, multi-output cup-shaped fluidic oscillator (200, 300, 400) is configured to generate a selected fluid spray from a plurality of (e.g., 2-8) fluid product inlets which are configured in interacting pairs and feed into a common interaction region of the fluidic nozzle geometry. Optionally, an outlet “A” can be positioned in the interaction region and allow for air entrainment into the interaction region or external oscillating spray streams to generate a foamed spray of fluid product.
