A shower jet outlet nozzle includes a hollow chamber (1), a lateral wall (2) delimiting the hollow chamber transversely to a nozzle longitudinal axis (D.sub.L), and a bottom (3) delimiting the hollow chamber in the direction of the nozzle longitudinal axis on an outlet side, which bottom is made of an elastic material and in which a jet outlet opening structure (4.sub.S) including one or a plurality of jet outlet openings (4) and having an open initial configuration, wherein the bottom is configured with the jet outlet opening structure thereof, under the effect of a shower fluid operating pressure in the hollow chamber, to deform in an elastically resilient manner and thereby to steadily increase an opening cross-section of the jet outlet opening structure with increasing shower fluid operating pressure within a normal operating pressure range. According to one aspect, the jet outlet opening structure (4.sub.S) is spaced apart from the lateral wall (2), and the bottom (3) on an inner side (3.sub.I) and/or on an outer side (3.sub.A) has a weakening pattern (5) with a lesser wall thickness as compared to an adjacent region of the bottom, wherein the weakening pattern is designed to deform in an elastically resilient manner under the effect of the fluid operating pressure in the hollow chamber (1).

A shower jet outlet device and a shower head equipped therewith have a jet disk with at least one jet disk opening and a jet outlet element disposed in the jet disk opening. The jet outlet element is pot-shaped with an outlet-side bottom, a side wall and a hollow chamber delimited by the bottom and the side wall. The bottom faces in the jet outlet direction and includes fine jet openings. The bottom and the side wall are made of an elastic material and the jet outlet element is configured to deform by bulging of its bottom and/or its side wall, in response to fluid pressure in the hollow chamber when operating.

A recirculating fluid flow system for an appliance includes a fluid pump that delivers process fluid through a fluid path. A tub is disposed within a cabinet and defines a processing space. The fluid path includes at least a portion of the processing space. The tub has an outlet that directs the process fluid toward the fluid pump. A sprayer assembly is coupled with the tub for directing the process fluid into the processing space. The sprayer assembly includes a spray head having a plurality of spray nozzles and an operable seam that extends through each spray nozzle of the plurality of spray nozzles. The operable seam is selectively separable to define a release opening that includes at least two spray nozzles of the plurality of spray nozzles.

A nozzle, including a support member and a nozzle boot surrounding at least a portion of the support member, the nozzle boot having a nozzle boot inlet and a nozzle boot outlet spaced from the nozzle boot inlet and a volume between the nozzle boot inlet and the nozzle boot outlet, the nozzle boot being expandable upon the introduction of fluid into the volume, and collapsible upon withdrawal of fluid from the volume. Also disclosed is a method of removing unwanted concrete from a surface by creating tensile stress to concrete adhered to that surface by causing the surface to expand, and a system for injecting fluid (s) into a rotating drum.

The present invention discloses a novel flexible spray nozzle sprayer face cap, rotatably installed at a head part of a garden water gun, configured to switch sprayed water types and structurally including a water division plate, a spray seat, and a main body sequentially fixed in a coaxial way. The novel flexible spray nozzle sprayer face cap is mainly characterized in that an embedded and fixed flexible spray nozzle is disposed in each water outlet small hole formed in the main body, and an outer end of each of the flexible spray nozzles respectively extends out of the water outlet small hole to be exposed, so that when the sprayer face cap rotates and switches to communicate passing water to a plurality of water outlet small holes, the passing water can be sprayed out from the flexible spray nozzle in each of the water outlet small holes. By designing the flexible spray nozzles, a range outer diameter of the water outlet small holes is increased, and water outlet position navigation of the water outlet small holes is also enhanced by using the flexible spray nozzles, so that the spray range is longer. At the same time, it is convenient to clean blocked impurities by the flexible spray nozzles. For example, when there are fine sandy impurities, the fine sandy impurities can be cleaned away only by slightly pulling the flexible spray nozzles by hand, so that the use quality of the sprayer face cap is greatly improved.

A dynamically-controllable spray nozzle, and associated control system and methods of use, has applicability in agricultural spraying and in other processes and devices in which spray nozzles are used. In an embodiment, a deformable nozzle may be compressed by one or more actuators to alter a nozzle’s exit orifice in a continuously variable manner.
