Abstract:
A spray gun cleaning system uses a separate cleaning fluid container which is substituted for the normal applied product container of the spray gun. The product feed tube of the spray gun is inserted into the cleaning fluid container, which is then sealably clamped to the spray cap of the spray gun. The container has a side opening, to which one end of a fluid hose is sealably attached. The other end of the hose is sealably attached to the nozzle portion of the spray gun. Pressurized air is discharged into the spray gun and this pressurization causes the cleaning fluid to circulate through the spray gun. As long as the pressurized air is discharged into the spray gun, cleaning fluid will automatically continue to circulate, without user involvement, through the sealed, closed circuit or path formed by the body of the spray gun, the fluid hose, the cleaning fluid container, and the feed tube. The cleaning system can thus automatically be allowed to operate as long as the user desires, in order to thoroughly clean the spray gun.
Abstract:
The invention relates to a spray pistol comprising a pistol body (1); a nozzle system (9) which is ranged on the pistol body (1); a compressed air supply channel (22, 23) which is arranged in the pistol body (1) and which comprises a valve system (17) for controlling the supply of compressed air to the nozzle system (9); a regulating device (6, 13) for regulating the supply of the substance to be sprayed; an actuating element (12) for actuating the valve system (17) and the regulating device (6, 13); a device (31, 33, 37) for regulating the supply of compressed air to the nozzle system (9); and a pressure-measuring device (35, 38, 39) for detecting and indicating the pressure in the compressed air supply channel (22, 23). The aim of the invention is to create a compact and handy spray pistol comprising a pressure-measuring device which is easy to monitor when spraying. In order to achieve this, the pressure-measuring device (35, 38, 39) is integrated into the device (31, 33, 37) used to regulate the compressed air supply.
Abstract:
A device and a method are provided for positioning an air cap of a pneumatically aided atomizer. The air cap has air horns extending from its face to provide flows of air to aid in atomizing and shaping the atomized particle stream. The method and apparatus contemplate providing a device having at least one first opening adapted to receive the horns and a first level for indicating when the horns received in the at least one first opening are in a desired orientation.
Abstract:
A paint gun washer includes a cabinet supported on a frame, the cabinet having an operable door in the forward wall and a switch connected to the door to continuously operate a vent in the cabinet while the door is open. A tank is mounted in the bottom wall of the cabinet and includes an operable door permitting access to the interior of the tank. Components to be washed with solvent are located within the tank, and a spray nozzle and/or hand brush are used to direct solvent on to the components. A valve connects the nozzle and/or brush with recirculated solvent from the tank. A separate rinse nozzle sprays the component with clean solvent. Foot operated switches activate pumps to dispense the solvent through the spray nozzle or brush. A filter panel is mounted in the cabinet spaced above the tank to prevent solvent from the tank from contacting the filter media.
Abstract:
The invention provides a spray gun comprising a main body 2, a spray head 6, an inlet 12 for a liquid to be sprayed, and an inlet 10 for a supply of a compressed air; the spray head comprising an air cap 40, a hollow nozzle member 36 having a nozzle tip 46 for dispensing the liquid, and means 58 for securing the air cap and nozzle member to the main body 2; the air cap 40 having a central aperture 52 through which atomising air is directed to atomise liquid dispensed through the nozzle tip to form a spray, and one or more lateral apertures 56 through which fan air is directed for shaping the spray to a desired pattern; the hollow nozzle member 36 having a radially extending weir 48 which together with a surface 51 of the main body defines an air distribution chamber 53 for receiving and distributing compressed air from the supply inlet 10; wherein an annular sealing member 38 having an annular wall is sealingly disposed between the radially extending weir 48 and the said surface 51 of the main body 2 so as to divide the air distribution chamber 53, whereby air passing into the chamber 53 thorough an opening 94 to one side of the annular wall is directed to the central aperture 52 of the air cap 40 and air passing into the chamber 53 through an opening 92 to the other side of the annular wall is directed to the lateral apertures 56 of the air cap 40.
Abstract:
A stripwise method of irrigation is disclosed, for use with an irrigation system comprising a length of flexible conduit to which a plurality of sprinklers are fixed, each sprinkler being fastened to a protective device which also keeps the sprinkler upright when the conduit is drawn across the ground. The conduit is connected to a water main riser positioned within the area to be irrigated and while maintaining water supply to the sprinklers, the conduit is drawn over the ground by a tow vehicle between set positions. In a preferred variation of the method consecutive set positions are on alternate sides of an imaginary line through the riser that bisects the area.
Abstract:
Apparatus and method for spray coating of a horizontally moving web uses a spray-down unit that sprays downwardly onto the web and a spray-up unit that sprays upwardly onto the web. Each unit has adjustable cut-offs that control the length of the spray pattern by intercepting end portions of the spray pattern. The cut-offs of each unit can be adjusted to block a spray emission opening so as to prevent the entrance of contaminants when the unit is not in operation. Fluid intercepted by the cut-offs is returned for re-use. Both units are supported on a frame, and the spray-down unit can be moved away from the spray-up unit.
Abstract:
An apparatus for applying fluid to a substrate which is movable relative to the apparatus. A slotted nozzle assembly of the apparatus communicates with a fluid supply and includes an elongated slot with an outlet aperture. The length of the slot may be varied using a stopper which can move in the slot and seal it off laterally. In another aspect, the entire slot can be shifted and fixed in the direction of the longitudinal axis of the slot using a guiding and adjusting device.
Abstract:
A machine (10) that can clean and spray coat the inside of a hollow pipe (14) can contain a support bar (16) and associated motors (6 and 8) with a moveable carriage (12) which mounts a thermal spray coating device (28) and/or an abrasion cleaning/profiling head (30) where a programmable controller external to the pipe is capable of controlling the motors (6 and 8).
Abstract:
An adaptor for use on a spray can which is normally operable by pushing down on a valve button with one's finger to open a valve and release pressurized contents in a sprayed pattern from a nozzle on the valve button. The adaptor releasably attaches to the top of the spray can and includes an actuator mechanism for holding the depressible valve button down in the open position, thereby allowing the pressurized contents of the can to be released from the nozzle without the use of the operator's finger. The actuator mechanism is operable between an on position, to hold the valve button down, and an off position to release the valve button in order to close the spray can valve when it is desired to interrupt spraying.
