Abstract: A nozzle for use with an adhesive spray apparatus includes a nozzle having an extended tip and an air cap having a diverging air passage terminating at an outlet concentric about the tip end. An adhesive outlet at the tip end is extended beyond the air outlet. Channels for swirling the air in the cap about the nozzle are provided in the cap around the nozzle. Highly viscous adhesives are sprayed in a uniform pattern without adhesive accumulation on the nozzle and disruption of pattern.

Abstract: The present invention pertains to improved atomization systems for comparatively higher viscosity liquid products. More particularly, the present invention provides an improved product delivery system which combines a pre-compression type pump mechanism with a nozzle having two or more orifices configured to discharge corresponding jets or streams of the product which impinge upon one another to provide a finely dispersed spray. The pre-compression pump mechanism ensures that the product will only be delivered when sufficient pressure is available for atomization. Regardless of the speed or authority with which the pump mechanism is actuated, pressure within the pump will accumulate without product discharge until a lower pressure threshold is reached, at which time a valve opens to permit product discharge with sufficient pressure for atomization. When the fluid streams impinge upon one another, the fluid is broken up into a finely dispersed mist which may then be directed toward the surface to be coated.

Abstract: By incorporating an alkyl polyol and a water soluble or emulsifiable silicone based compound into a moderately viscous gel-type hair conditioning composition, a hair conditioning gel formulation is attained which is able to be delivered in a spray mist pattern using conventional small diametered pump spray nozzles. Preferably, the alkyl polyol has a carbon content ranging between 2 and 8, and the hydroxyl ion content ranges between 2 and 7 and are not spaced apart by more than 4 carbon atoms. It has been found that by employing this invention, the resulting gel formulation is able to be dispensed consistently, repeatedly and easily in a liquified spray mist through a pump nozzle having apertures ranging between about 0.010 and 0.030 mm.

Abstract: A device is used for spraying and atomizing a liquid which is held in a container which can be emptied by air pressure. If in a device of this kind a liquid nozzle projects into a mixture nozzle disposed coaxially in front of it, so that an annular space provided for air around the liquid nozzle is open at the front towards the mixture nozzle, the feed paths for liquid and for air must not be transposed. Such transposition occurs if the container is held upside-down during spraying. In order to avoid this disadvantage two annular spaces are provided, from which passages lead to a mixture nozzle. The two annular spaces communicate with one another via throttle slots. Because of the two annular spaces the liquid can also be sprayed when the container is upsidedown.

Abstract: Within the inner sleeve (7) of a discharge connection (5), a discharge head (1) receives approximately over its entire length the shaft (13) of an inner body (12) in such a way that the latter in the vicinity of the end of the inner sleeve (7; ) forms a connecting member (16) separate therefrom and located freely within a main body (2) serving as a plugging member for connection to a discharge apparatus.

Abstract: A spray nozzle designed to produce a spray or mist containing a high concentration of bubbles. Such a spray is particularly useful in mixing liquid fuel and air for burning within a combustion chamber, as for example in a gas turbine engine. The novel design includes a pair of swirl chambers generally axially aligned within the nozzle. Fuel or other liquid enters the first or forward swirl chamber in a generally tangential and laminar flow pattern, passes into the second or rearward chamber through an interconnecting orifice. Violent liquid and air mixing occurs in the second chamber and the mixture is then expelled as an aerated spray through the interconnecting orifice, the first chamber and a discharge orifice.

Abstract: A hollow elongate pushbutton receives a nozzle rod 2, and is mounted at a mid-portion on the valve rod of a liquid spray pump intended to operate under pressures on the order of more than 100 bars, and at a repetition rate of 50 Hz or more. The center of gravity of the pushbutton and nozzle rod assembly lies on the axis of the valve rod, to avoid vibrations during use.

Abstract: A multiple purpose water spray gun comprises: a main body, a revolving ring, a water control rod, a press trigger, a seal plate and an adjusting knob, wherein at the front end of the revolving ring, five nozzles of different types are arranged for various purposes. One of the nozzles is a rain-drop nozzle consisting of a central recessed hole where water is led in, a plurality of grooves which are radially disposed around the recessed hole and by each of which the water is conducted into a different large opening to then pass through a small hole to spray out as mist. The press trigger and the main body have matched lugs for direct pressing together to save assembling cost; leakage prevention rings are provided along the front and rear ends of the water control rod, to ensure perfectly tight seals.

Abstract: An electrostatic powder spray gun is provided with an arcuate nozzle tube forming a curved passage between an inlet and outlet orifice. A mixture of powder particles and a carrier gas injected into the inlet orifice is subjected to a swirling motion prior to exiting the outlet orifice. This swirling motion is caused by helical grooves cut into the inside surface of the arcuate tube adjacent to the outlet orifice. An electrode imparts an electrical charge to the particles as they exit from the nozzle tube.

Abstract: A fuel injection valve is proposed for fuel injection systems of internal combustion engines, which serves to supply fuel into the intake tube of the engine. The injection valve includes a movable valve element which cooperates with a fixed valve seat, downstream of which are provided horizontal fuel guidance bores which discharge tangentially into a spin chamber. The spin chamber is disposed so that it widens conically in the flow direction. The fuel guidance bores simultaneously serve as metering bores. The spin chamber causes an axial speed component to be imparted to the fuel entering via the fuel guidance bores. As a result, the dwell time of the metered fuel within the spin chamber is short, and even in the case of quite short injection pulses, the fuel is still sufficiently well prepared.
