A nozzle including an elongate body and a nozzle outlet subassembly. The elongate body includes a first passageway. The nozzle outlet subassembly is disposed at least partially within the first passageway. The nozzle outlet subassembly includes a nozzle terminal and a diffuser. The nozzle terminal defines a second passageway and a spray opening. The diffuser defines a diffusion opening that is proximate the spray opening.

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.

The invention pertains to a plastic spray gun nozzle having an orientable spray pattern achieved by rotational movement of the repositionable plastic nozzle.

Apparatus and methods for providing a desired volumetric conditioned airflow rate and for reducing noise level, airflow recirculation and airflow separation are disclosed. An example apparatus includes a nozzle housing having a pair of opposing sidewalls and a front and back wall that define an airflow passage. The airflow passage has a centerline extending between the inlet and the outlet and has a plurality of cross-sections taken perpendicular to the centerline that collectively define a smooth contour along a length of the airflow passage. The cross-sections each have a thickness between the front and back wall that is greater at side edges than at the centerline. The thickness of the cross-sections decreases along a length of at least a first portion of the nozzle housing. A width of each of the cross-sections between the sidewalls increases along the length of at least the first portion of the nozzle housing.

A nozzle arrangement includes a nozzle inlet part having an inlet duct for liquid under pressure, and a nozzle outlet part which is displaceable relative to the nozzle inlet part between a first and second position and which has a high-pressure nozzle and a low-pressure nozzle each configured as a fan-jet nozzle. In the first position, only the high-pressure nozzle is connected to the inlet duct and in the second position the high-pressure and the low-pressure nozzles are connected to the inlet duct. The at least one low-pressure nozzle is arranged radially offset to the high-pressure nozzle, and the nozzle outlet part has a connecting nipple via which the high-pressure nozzle is in a flow connection with the inlet duct and which interrupts or allows a flow connection of the inlet duct with the low-pressure nozzle depending on whether the nozzle outlet part is in the first or second position.

Nozzle orifice shapes and configurations associated with regulating and directing a flowing body of water over a water attraction riding surface for performing board-riding maneuvers is described. The nozzle orifice shapes and configurations according to the present invention includes shapes and configurations allowing for a flow of water over a ride surface which may include complex shapes which do not lend themselves to use with existing nozzle technologies. The present invention also includes nozzle arrays which may be made up of two or more nozzles arranged substantially adjacent or within close proximity to one another to create beneficial flow characteristics for performing board riding maneuvers on a complexly shaped riding surface.

A unitary nozzle for a washing machine appliance includes an inlet body and an outlet body that are integrally formed together. The outlet body defines an outlet conduit with a first cross-sectional area at an entrance of outlet conduit and a second cross-sectional area at an exit of the outlet conduit. A shape of the second cross-sectional area is substantially arcuate. A related method for forming a unitary nozzle of a washing machine appliance is also provided.

A spray nozzle assembly includes a body and a spray tip supported on the body. The spray tip includes a fluid inlet passage that terminates in an end wall. An annular discharge passage is arranged in the spray tip downstream of the end wall and the fluid inlet passage. The annular discharge passage defines a circular ridge in an external downstream surface of the spray tip. A plurality of discharge orifices through which fluid is discharged from the spray tip provided in the circular ridge. Each discharge orifice communicates with the annular discharge orifice and is formed in a respective notch in the circular ridge with each notch having at least one sidewall that defines a deflector surface for the respective discharge orifice.
