A fluid mixing apparatus for association with an air atomizing spray gun is disclosed. The fluid mixing apparatus comprises a fluid manifold adapted for attachment to the handle of an air atomizing spray gun and includes static mixer means interconnecting the fluid manifold with the spray fluid inlet of the air atomizing spray gun. The fluid manifold comprises a fluid passage means interconnecting a plurality of inlet ports and communicating with an exit port which is connected to the static mixture means. The individual components of a multiple component sprayable fluid are separately introduced into the manifold through individual ones of the manifold inlet passages and are flowed through the manifold passage to be intimately intermixed by the static mixer means prior to being introduced into the sprayable fluid inlet port of the air atomizing spray gun.
A system for mixing multi-component high viscosity coating and for spraying the mixed coating onto a surface. The coating components are combined by folding together in a desired ratio and subsequently mixing in a gear mixer.The mixed components are atomized and discharged from a spray gunm onto the surface. A solvent system is provided for purging the mixed coating either from the entire system or only from the spray gun.
A fragrance dispensing machine for full service car wash installations administers a carefully controlled amount of fragrance concentrate to precisely scent customer vehicles. The machine is preferably mounted upon a wall adjacent the car wash lane for convenient access vehicles being washed. An associated hand-operated applicator gun interconnected with the machine administers a uniform dose of fragrance concentrate during each application, which is outputted as a fine mist. The machine cabinet provides storage space for bottles of fragrance concentrate. An external source of air pressure is applied to the cabinet for generating the mist. An elongated conduit interconnects the applicator gun and the machine and separate conductive tubes within the gun conduit individually transmit air and fragrance concentrates to an atomizer manifold disposed within the applicator gun. Mixing of air and fragrance concentrate is performed within the atomizer through vacuum venturi suction. High pressure air driven through the atomizer and the gun barrel sucks fragrance concentrate out of an adjacent fragrance manifold passageway. Fragrance misting is performed in the applicator gun to minimize fragrance contamination. Operation is monitored and controlled by the machine circuit remotely disposed within the cabinet.
An apparatus for effecting rapid color change of the color component of a multiple component sprayable fluid to be applied using a manual spraygun. The apparatus includes primary and secondary color changer means, each having a manifold with a through passage. Color component to be applied to a substrate enters the primary color changer manifold and passes out of that manifold through a metering pump and flow sensor to the secondary manifold from which it passes through a color outlet line and ultimately to a spraygun. Apparatus is adapted to effect rapid flushing and color change by sequencing color inlet and outlet valves and flush and dump valves so as to effect rapid flush of the lines and connection of the subsequently filled color changers to color outlet lines.
An apparatus for a liquid and pressurized gas includes a gas inlet hose for conducting the pressurized gas therethrough, a liquid inlet hose, extending through the interior of the gas inlet hose, for conducting the liquid therethrough, a hose separator connected to an end of the gas and liquid inlet hoses, a gas outlet hose connected through the hose separator so as to be in fluid communication with the gas inlet hose for further conducting the pressurized gas therethrough, a liquid outlet hose, separate from the gas outlet hose, connected through the hose separator so as to be in fluid communication with the liquid inlet hose for further conducting the liquid therethrough, and a main outlet hose connected to and in fluid communication with the liquid outlet hose and the gas outlet hose. The apparatus further includes a first valve positioned within the liquid outlet hose to regulate flow therethrough and a second valve positioned within the gas outlet hose to regulate flow therethrough.
A small and lightweight compressor has a motor which generates rotational drive which is converted into reciprocating movement to actuate an air compressing mechanism to thereby discharge compressed air. Three or more air compressing members are successively operated with a phase difference therebetween to thereby continuously discharge a smooth current of compressed air out of a discharge hole. The compressor can be part of a spray apparatus with an air brush in which a movable needle valve is inserted in a liquid path. The needle is moved by operation of a rod 70. Compressed air from the compressor is communicated with the air path to thereby spray the liquid. The air brush has a control surface which is the upper surface of a base portion of the rod, which is pivotable with respect to the body. A sliding member is axially movably disposed so that when the rod is actuated (manually usually), the amount of movement of the rod (i.e. its range of movement) can be adjusted by making the lower end of the sliding member abut against the control surface.
