The present invention provides a cleaning machine capable of selecting a spray head independently of a rotational phase of a nozzle. The cleaning machine includes a slide, a pump, a main valve, a nozzle switching valve, a compressed air source, a swivel joint, a motor, and a nozzle block. The nozzle switching valve has an inflow chamber, a first chamber, a second chamber, a stem, a conical first valve element abuttable against the first valve seat, a conical second valve element abuttable against the second valve seat, a piston, and a spring. The swivel joint has a swivel housing, a swivel shaft, a first nozzle flow path and a second nozzle flow path. The nozzle block has a first nozzle connected to the first nozzle flow path and a second nozzle connected to the second nozzle flow path.

An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

A dispensing assembly for a snow generator has a fixed structure (4) having a circular opening (5) extending along the longitudinal axis (A1); a rotor (6) extending along the longitudinal axis (A1), which has one free end (7) at the circular opening (5), and is configured to rotate around a rotational axis, preferably coinciding with the longitudinal axis (A1); and a water supply assembly (10), configured to supply water at a given pressure within the fixed structure (4), at the free end (7) of the rotor (6); the free end (7) of the rotor (6) being coupled to the circular opening (5) of the fixed structure (4) so as to delimit, together with the fixed structure (4), an annular gap configured to guide a jet of atomised water towards the outside of the dispensing assembly (2).

A composite nozzle comprises: a housing having formed at one side thereof a cleaning liquid inlet through which the cleaning liquid is introduced, an installation port communicating with the cleaning liquid inlet at the other side thereof, and an air inlet path communicating with an air inlet on the outer side of the installation port; an opening and closing valve installed so as to be slidably movable toward one side and the other side in the installation port formed in the housing; an elastic body such as a spring that slidably moves the opening and closing valve while elastically supporting the opening and closing valve; and a cap which sprays the cleaning liquid to the outside from the other end of the housing in which the opening and closing valve is installed so as to be slidably movable in one direction and the other direction of the installation port.

There is provided a spray gun configured to atomize a liquid by using a compressed gas. The spray gun comprises: a gas cap configured to inject the compressed gas; and a liquid nozzle configured to inject the liquid, wherein the gas cap comprises a center gas flow path that has an opening provided in a neighborhood of the liquid nozzle; and multiple pairs of side face gas ports provided outside of the opening, each pair of the side face gas ports being placed at positions symmetric to each other across a center of the liquid nozzle and being directed toward a center in an injecting direction of the liquid nozzle, and wherein control is made to individually regulate a pressure of the gas to be injected from each pair of the side face gas ports.

The disclosure relates to a nozzle device for emitting an emission medium onto a component, preferably for emitting the emission medium onto two side faces and preferably an end face of a fold, an edge or a transition joint of the component. The nozzle device comprises an opening configuration for emitting the emission medium and is distinguished particularly in that the opening configuration comprises at least two openings for emitting at least two jets of the emission medium and the at least two openings are oriented inwardly so that the at least two jets approach one another toward the emission side.

The disclosure relates to a nozzle device for emitting at least one emission medium onto a component, preferably onto a fold, an edge or a transition joint of the component. The nozzle device comprises at least two nozzle plates arranged adjoining one another, wherein a first nozzle plate comprises at least one opening for emitting at least one emission jet and a second nozzle plate comprises at least two openings for emitting at least two emission jets.

The disclosure concerns a spray bottle assembly for use with an atomized-spray dispensing device. The spray bottle assembly generally includes a bottle containing an amount of cosmetic composition, a release mechanism having a port associated therewith, an insert with an insert lumen configured to engage the port for communicating the cosmetic composition therethrough, a nozzle for configuring a stream of the cosmetic composition expelled from the spray bottle assembly, a mixing chamber for mixing compressed air with the stream of the cosmetic composition, and a spray aperture for communicating atomized spray. The spray bottle assembly is designed for use with equipment having corresponding release elements for engaging the insert and release mechanism of the bottle.

According to an embodiment of the present invention, a substrate processing apparatus including: a chamber in which a process is performed on a substrate; a susceptor installed in the chamber to support the substrate; and a showerhead installed above the susceptor, and the showerhead includes: a plurality of inner injection holes defined in an inner area corresponding to a portion above the substrate and injecting a reaction gas downward; and a plurality of outer injection holes defined in an outer area corresponding to a portion outside the inner area and injecting an inert gas along an inner wall of the chamber.
