A dual turbine showerhead provides multiple spray modes emanating from the head. The showerhead includes an inlet orifice, a backplate, a first turbine located side-by-side with a second turbine, a faceplate forming a first orifice group and a second orifice group, a first fluid channel in fluid communication with the first and second turbines and the first orifice group, and a second fluid channel in fluid communication with the second orifice group. In another embodiment, the showerhead includes first and a second turbines located side-by-side and a valve body that channels a fluid to the first turbine and the second turbine. In another embodiment, the showerhead includes a first and a second turbine located side-by-side along a centerline of the showerhead, a corresponding outlet region is arranged along the centerline and additional outlet regions are laterally spaced therefrom.

A spray nozzle for a system for dispensing a pressurized product is provided with a pushbutton. The nozzle includes a dispensing orifice and a vortex chamber emerging on the dispensing orifice. The chamber includes a conical part defined by a conical side surface. The conical side surface converges from an upstream end toward a downstream supply end of the dispensing orifice. The nozzle further includes at least one supply channel of the vortex chamber, each supply channel emerging in the upstream end of the conical part, the conical side surface having at least one stepped portion provided with multiple levels.

The disclosure provides a bidet nozzle assembly, which includes a nozzle housing; a nozzle, the nozzle having a distal end and a proximal end, the nozzle including a channel through to the distal end and to the proximal end, the channel having a first channel opening at the distal end and a second channel opening at the proximal end; a nozzle insert, the nozzle insert located at the first channel opening of the distal end of the nozzle, the nozzle insert having at least one nozzle hole; and a nozzle cap.

A spray nozzle chip is presented having: a first layer provided with a first layer orifice, a mechanically flexible nozzle layer provided with a nozzle orifice, the spray nozzle chip having a valve functionality obtained by movement of the nozzle layer relative to the first layer due to pressure changes, wherein the nozzle orifice is closed when the nozzle layer is in a default non-pressurised state and wherein the nozzle orifice is opened and set in fluid communication with the first layer orifice when the nozzle layer is deformed due to pressure during a spraying operation, and wherein the spray nozzle chip further has a sealing layer configured to rupture when the nozzle layer is deformed due to applied pressure during a spraying operation.

A nozzle hole of a nozzle plate is connected to a fuel injection nozzle of a fuel injection unit through a swirl chamber and first and second fuel guide grooves opened to the swirl chamber. The swirl chamber is an oval recess provided with the nozzle orifice in its center. A first fuel guide groove is opened to one end side of a major axis of the oval recess, and a second fuel guide groove is opened to the other end side of the major axis of the oval recess. The first and second fuel guide grooves are formed such that the same amount of fuel flows to the swirl chamber. The same amount of fuel flowing from the first and second fuel guide grooves to the swirl chamber is guided to the nozzle orifice at the same time while revolving inside the swirl chamber in the same direction.

An actuator for dispensing the liquid contents of a container in the form of a spray includes an actuator cap, an axial spray channel with an orifice for spraying the contents of the container, and an axial feed channel for connection a container outlet to the spray channel. A breakup wedge is provided in the feed channel such that it splits the feed channel into two sub channels, each connected via a side inlet opening with an inlet portion of the spray channel. Thus, in use, a flow of content is split into two sub flows by the breakup wedge, which sub flows subsequently collide in the inlet portion of the spray channel causing a turbulent flow of the liquid product in the inlet portion of the spray channel, which turbulent flow is guided by the spray channel towards and out of the dispensing opening.

The disclosure relates to devices, systems, and methods using a helical nozzle. The devices, systems, and methods can include a helical nozzle having a plurality of flow channels that rotate around a center axis of the nozzle. The rotated channels can impart a helical flow to fluid moving through the nozzle thereby speeding dissolution of material within a container connected to the nozzle.

An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

The present invention is intended to solve a problem that a coating film has an uneven thickness in the case where a coating target 1 has a stepped portion extending in a predetermined direction on its coating surface. To solve the problem, a follow-up coating is performed along the stepped portion S extending in the predetermined direction after coating of the entire coating surface of the coating target 1 so that paint mist adheres more to a relatively-recessed side of the stepped portion S.
