摘要： A method and apparatus for spraying liquid coating material containing supercritical fluid or liquified gas as a diluent comprises a spray gun having internal passages which transmit the liquid coating material under high pressure from an inlet (64) to a nozzle (50) at the tip of the gun (14) and then to an outlet (66) so that the liquid coating material can be continuously recirculated. A relatively short flow discharge path is formed between the internal passages in the spray gun (14) and the nozzle (50) to avoid the formation of an area of ambient or reduced pressure so that the supercritical fluid of liquified gas is substantially maintained in solution in the liquified coating until it is discharged from the gun (14). A pressure regulator (128) is provided to maintain a substantially constant pressure drop across the inlet (64) and outlet (66) of the gun (14) to induce flow of liquid coating material through the gun (14), and to permit several guns (14) to be connected in series without creating a substantial pressure drop therebetween.

摘要： An air atomizing nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly is made of plastic parts and includes an air cap having a central bore which surrounds a fluid nozzle tip. The nozzle has a nut formed on its forward end to facilitate threading of the rearward end of the nozzle tip into a threaded bore of the gun body. Formed on the front part of the nozzle, either as a part of the nut or a cylindrical surface adjacent the nut, is an accurately machined surface engageable in press fit relationship with a mating accurately machined bore of the air cap. These mating press fit surfaces center the bore of the air cap relative to the nozzle tip so as to leave an annular, evenly dimensioned air flow passage surrounding the nozzle tip and defined between the nozzle tip and the bore of the air cap. The air cap is retained in a one-piece resilient retaining ring by snapping the air cap into an annular lip of the retaining ring. The retaining ring is then threaded onto the gun body to secure the nozzle assembly onto the gun body.

摘要： A nozzle assembly for spray coating apparatus such as an electrostatic spray gun includes an air cap (50) having a central bore (52) which engages a nozzle member (26). The bore has a plurality of uniformly dimensioned axially aligned gas flow passages (62) evenly spaced about its circumference and a plurality of radially inwardly extending ribs (64) therebetween.
In order to obtain uniform atomization of coating material and prevent the spray pattern to be badly distorted the side of a bore engages the outside surface of the nozzle member to positively align its centre axis on the axis of the central bore. The air cap and nozzle member thus cooperate to form a plurality of uniform gas flow passages around the nozzle (38) thereby producing a fineiy atomized uniform spray pattern of coating material emitted from the nozzle member.

摘要： A continuous coater of the type having a conveyor extending through a coating booth (11) where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth (11) has an air flow control vestibule (12, 13) located adjacent the entrance and exit ports. Each vestibule (12, 13) is connected to an air flow exhaust system (15, 16) and is so configured that it is operative to draw air (65) almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibul entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain (108) which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.

摘要： An air atomising nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly is made of polyamide-imide («Torlon») plastic parts and includes an air cap having a central bore which surrounds a fluid nozzle tip. The fluid nozzle tip has a nut formed on its forward end to facilitate threading of the rearward end of the nozzle tip into a threaded bore of the gun body. Formed on the front part of the nozzle, either as a part of the nut or a cylindrical surface adjacent the nut, is an accurately machined surface engageable in press fit relationship with a mating accurately machined bore of the air cap. These mating press fit surfaces centre the bore of the air cap relative to the nozzle tip so as to leave an annular, evenly dimensioned air flow passage surrounding the nozzle tip and defined between the nozzle tip and the bore of the air cap. The air cap is retained in a one-piece resilient retaining ring by snapping the air cap into an annular lip of the retaining ring. The retaining ring is then threaded onto the gun body to secure the nozzle assembly onto the gun body.
摘要翻译：公开了一种用于静电喷枪的空气雾化喷嘴组件。喷嘴组件由聚酰胺酰亚胺（“Torlon”）塑料部件制成，并且包括具有围绕流体喷嘴尖端的中心孔的空气帽。流体喷嘴尖端具有形成在其前端上的螺母，以便于将喷嘴尖端的后端螺纹连接到枪体的螺纹孔中。形成在喷嘴的前部，作为螺母的一部分或与螺母相邻的圆柱形表面，是精确加工的表面，可与压盖配合关系与空气帽的匹配精密机加工孔相接合。这些配合的压配合表面使空气帽的孔相对于喷嘴尖端居中，以便在喷嘴尖端周围留下环形且均匀尺寸的气流通道，并限定在喷嘴尖端和空气帽之间。空气帽通过将空气盖卡入保持环的环形唇缘中而保持在单件弹性保持环中。然后将保持环拧到枪体上，以将喷嘴组件固定在枪体上。
