A nozzle having intersecting perpendicular inlet and outlet axes is constructed with a cylindrical whirl chamber into which liquid is introduced from a transition passage. The latter is bounded by a flat surface of substantial width, with one end of the flat surface being tangent to the cylindrical surface defining the whirl chamber. In cross-section perpendicular to the flat surface and to the direction of liquid flow in the transition passage the latter is bounded by a straight flat section an...

In a pressure atomized oil burner having air louvers to swirl primary air, a long narrow flame is produced without reducing heat release by using a nozzle tip having cylindrical ducts drilled at a compound angle in the direction of the air swirl in addition to the main cone angle.

A mechanical breakup aerosol valve button or actuator with an annular feed chamber which feeds passageways leading into a central swirl chamber immediately ahead of the forward portion of a cylindrical terminal orifice feed post which includes a centrally disposed cavity formed in the face thereof and immediately behind a recessed terminal orifice contained within a terminal orifice which cooperate to produce a homogeneous spray pattern.

The 90.degree. rotation nozzle assembly for a trigger sprayer comprises a nose bushing and a nozzle cap rotatably mounted on the nose bushing. The nose bushing has a front core with a front face and a generally cylindrical periphery. The generally cylindrical periphery has first, second and third, angularly spaced apart, longitudinally extending channels therein which open onto the front face of the core and extend rearwardly therefrom. The nozzle cap includes a front wall having a back side and...

An aerosol valve actuator button having a swirl chamber for mechanical breakup of the product stream proximate the spray discharge orifice is constructed in two pieces, an exterior body piece including a central cavity having wall portions including a depression forming the swirl chamber surrounding a discharge orifice, and an interior insert or plug adapted to be received in the cavity of the body piece, the insert piece including a valve stem receiving socket and product flow channels.

A spray head for discharging a spray pattern in which the entire inner portion of the pattern has liquid atomized therein. A plurality of orifice channels receive fluid radially from a relatively large central supply channel. Preferred embodiments are disclosed in which the spray head is a unitary molded component having no moving parts. Other preferred embodiments are disclosed in which the spray head includes an adjustment feature whereby a two-part molded head provides a desirable cone-shaped...

A collapsible dispensing container tube having a thermoplastic headpiece united to a tubular body with a one-way valve insert positioned in the upper part of the tube to perform an anti-suck-back function by blocking the flow of air into the tubular body when manual pressure on the tubular body is released after the dispensing of a desired portion of product from the tube.

An extrusion nozzle, especially suitable for texturing proteinaceous materials, comprising an elongate body having a side wall defining an axial passage, at one extremity of the body the side wall having longitudinal slits defining at least two fins the free ends of which are turned inwardly towards the longitudinal axis of the passage. Other features of the invention are described in the following specification.

The atomizer has a conduit for distributing liquid from a single supply inlet to a plurality of feed holes spaced apart from one another. The cross-sectional area of the distribution conduit decreases at increasing distances from the inlet, thus promoting even distribution of liquid among the multiple feed holes at both high and low flow rates. The rate of decrease of cross-sectional area preferably is made inversely proportional to the viscosity of the liquid. In its preferred form, the atomize...

A mechanical breakup aeroso valve button or actuator with an annular feed chamber which feeds chordal passageways leading into a central swirl chamber behind a recessed terminal orifice contained within an insert, whereby spray pattern and flow rate are controllable.
