A spray applicator is disclosed. The spray applicator can include a carrier body including a number of contact surfaces and at least two nozzle bodies. Each nozzle body can be fastened on one of the contact surfaces and have a spray slit for producing a spray jet fanned out transversely to a center plane. the center planes can cross one another along a straight line. The straight line can extend outside the carrier body. The contact surfaces can face the straight line and be offset with respect to one another in the direction of the straight line.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

The present disclosure relates to a soot blower including: a lance tube which includes one end that reciprocally moves in one direction on a surface of an inlet port of a flow path of the tubular heat exchanger; a drive unit which is connected to the lance tube and reciprocally moves and rotates the lance tube in the one direction; a first nozzle which is connected to the one end of the lance tube and discharges steam to the inlet port; and a second nozzle which is disposed adjacent to the first nozzle and connected to the one end of the lance tube and discharges solid particles to the inlet port, and the present disclosure relates to a method of cleaning a tubular heat exchanger by using the soot blower.

A dispensing closure for a squeeze-type container produces a fan-type spray in a low pressure environment. The dispensing closure includes a closure body having an upper deck and a skirt depending from the upper deck. The skirt is configured and arranged to attach to a product container, such as a squeeze-type container. A flow conduit extends from an interior of the closure body and through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit has an entrance orifice and an exit orifice. The flow conduit has an inner wall extending between the entrance orifice and the exit orifice. The flow conduit and the closure body are integrally formed. The flow conduit includes a tip portion with an exit orifice defining a shape to provide a fan-type spray in a low pressure environment.

Devices deliver the content of an aerosol, and are used in powder-actuated tools. A spray nozzle includes a cylindrical housing having, at a first end, with a base having a mounting bore that extends inside said housing so as to receive a barrel of a powder-actuated tool. The nozzle is equipped with a securing means. The base includes lobes that lie opposite one another in a single plane. A peripheral section of the second end of the housing is located on the same side as one of these lobes and has a curved projection with a rounded outer surface and an upward taper to form a common top surface with an additional cylindrical projection partially embedded into the inner surface of the curved projection. A V-shaped groove in communication with an axial opening of the second end of the housing extends on a free side of the additional projection.

A rotary water outlet mechanism and a flushing device, including a housing having a gradually changing curved surface and a water outlet part connected to one end of the housing. A water separator provided with at least one oblique through hole, an impeller and a water guide are provided in sequence in a water flow direction between the housing and the water outlet part. The impeller is in transmission connection with the water guide rotatably connected with the water outlet part, one end of the water guide is provided with a water outlet. The water flow enters the housing, and under a guidance of the gradually changing curved surface of the housing, the water flow passes through the oblique through hole, and flows through the impeller and drives the impeller to rotate, such that the water guide rotates to generate a rotating water flow.

A paving machine includes a machine frame, a drive assembly, including at least two tracks, each driven by a drive wheel and one or more idlers, and a paving material delivery assembly including a hopper, a conveyor assembly, an auger, and a screed. The paving machine also includes a tank of emulsion fluid, a spray bar positioned on an underside of the machine frame between the at least two tracks and fluidly coupled to the tank to deliver the emulsion fluid to a ground surface.

Spraying heads may be used in spray guns for applying a pressurized aerosol material in the form of jets or spray. A spraying nozzle for spraying a polyurethane material includes a cylindrical body provided, on a first end, with a base having a mounting aperture extending into the cylindrical body, forming a cavity for arranging a head of a gun. The base of the nozzle is in the form of oppositely-disposed leaves. A second end of the body is provided with a cylindrical shoulder, a through-bore of which is communicated with a V-shaped and laterally non-closed recess at the region of an outlet of the sprayed material. Oppositely arranged plate-like protrusions adjoin a lateral surfaces of the cylindrical shoulder. A mounting aperture end which adjoins the base has a circumferential cut. The spraying nozzle is provided with an attachment means used when in an inoperative position.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.
