An all-plastic, continuous trigger sprayer is contemplated that avoids the use of metal parts, elastomers, or other disparate and non-recyclable materials. A reservoir diaphragm is provided within the sprayer head, interposed between the actuation mechanism and the outlet, so as to ensure a steady flow of dispensed fluid is delivered even after actuation has ceased.

A swirler-ferrule assembly includes a radial swirler, a ferrule, a fuel nozzle, and a surface feature. The radial swirler includes a primary swirler vane having a primary air passage and a secondary swirler vane having a secondary air passage. The ferrule may be connected to the radial swirler. The surface feature may be located on the primary swirler vane and/or the ferrule. The surface feature may be configured to direct an air flow through the primary air passage away from a recirculation zone located upstream of the primary swirler vane. The surface feature has a trailing end and a distal end, and the fuel nozzle is axially aligned with the trailing end of the surface feature or is located axially downstream of the trailing end of the surface feature. The surface feature may have a plurality of grooves.

A showerhead engine internally swirls water within a swirling chamber. Multiple swirling chambers may be used, each separated from one another. The water is swirled angled through holes in a mid plate. As the water passes through the angled holes, it is projected out an angle. The water then contacts the swirling chamber wall and continues to follow the curvature of the wall. The curved wall paired with the angled entry causes the water to continue to swirl within the swirling chamber. The water is released out of the swirling chamber through slots, which allow the water to retain the angular velocity at a discharge angle.

The water outlet device comprises a water outlet component and a control mechanism, the water outlet component comprises a spherical chamber, a bottom of the spherical chamber comprises a water outlet hole, a top of the spherical chamber comprises a first water inlet, a side wall of the spherical chamber comprises a second water inlet, discharging water spray from the water outlet hole is controlled by flow rate variations of the first water inlet and the second water inlet, and the control mechanism cooperates with the first water inlet and the second water inlet to steplessly adjust the flow rate variations of the first water inlet and the second water inlet.

A nozzle includes a shell, a distributor, a panel and a collar. The distributor is inserted in the shell. The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.

The present disclosure relates to a nozzle for discharging compressed air having a circumferential surface section which extends from a feed end to a discharge end and extends at least partially axially, and an end section produced in one piece, which extends radially inward from the circumferential surface section at the discharge end. In order to allow efficient and targeted compressed air discharge, the present disclosure envisages that a plurality of helical passages extend through the end section, each of which slopes in a tangential direction, at least in some section or sections, and into each of which a first discharge opening for compressed air opens.
