Abstract

La presente invención se refiere a un atomizador giratorio para rociar un fluido de revestimiento, que comprende: un alojamiento que tiene una campana atomizadora soportada en forma giratoria adyacente a un extremo del alojamiento, incluyendo la campana atomizadora un miembro generalmente en forma de copa que tiene una superficie de flujo delantera anular que se extiende generalmente hacia afuera con relación a un eje de rotación de la campana y que termina en una porción de orilla externa, desde la cual se descarga el fluido de revestimiento; una placa contra salpicadura anular, asegurada dentro del miembro en forma de copa y que define una superficie trasera y una superficie delantera, teniendo la superficie trasera una porción central adaptada para recibir un suministro de fluido de revestimiento y dirigir el fluido de revestimiento desde la porción central, a lo largo de la superficie trasera, hacia otra porción de la placa contra salpicadura, teniendo la porción central de la superficie trasera una proyección generalmente cónica que se extiende hacia afuera desde la misma; un primer medio de pasaje que se extiende a través de la porción externa de la placa contra salpicadura para suministrar el fluido de revestimiento a la superficie de flujo delantera anular del miembro en forma de copa; y por lo menos un segundo medio de pasaje que se extiende en línea recta a través de la placa contra salpicadura, para suministrar una porción del fluido de revestimiento a una porción central de la superficie delantera de la placa contra salpicadura, teniendo el segundo medio de pasaje una entrada en la proyección cónica, separadadel eje; un medio de tubo de alimentación que tiene un extremo conectado a una fuente de fluido de revestimiento y un extremo opuesto colocado sobre el eje adyacente a la proyección, para suministrar fluido de revestimiento al mismo; una tapa de aire de conformación anular, asegurada en relación a un extremo del alojamiento y que tiene una superficie externa que se extiende desde el alojamiento hasta una porción periférica de la campana; y un anillo de aire de conformación anular asegurado en relación a la tapa de aire de conformación y que tiene una superficie interna en relación encarante con la superficie externa de la tapa de aire, y que se extiende hacia la porción periférica de la campana; cooperando la superficie externa de la tapa de aire y la superficie interna del anillo de aire para definir una primera cámara anular para recibir un suministro de aire de configuración a presión, una formación anular de aberturas para recibir dicho aire de conformación de la primera cámara, una segunda cámara anular para recibir el aire de conformación de la primera cámara, a través de las aberturas, y un espacio anular abierto, adyacente a la porción periférica de la campana, recibiendo el espacio anular el aire de conformación de la segunda cámara y dirigiendo este aire de conformación hacia la porción periférica de la campana, en un patrón o modelo de anillo uniforme delgado.The present invention relates to a rotary atomizer for spraying a coating fluid, comprising: a housing having a rotationally supported atomizing hood adjacent one end of the housing, the atomizing hood including a generally cup-shaped member having an annular forward flow surface that generally extends outwardly relative to an axis of rotation of the bell and ending in an outer edge portion, from which the coating fluid is discharged; an annular backsplash, secured within the cup-shaped member and defining a rear surface and a front surface, the rear surface having a central portion adapted to receive a supply of coating fluid and direct the coating fluid from the portion central, along the rear surface, towards another portion of the backsplash, the central portion of the rear surface having a generally conical projection extending outwardly therefrom; a first passageway means extending through the outer portion of the backsplash to supply the coating fluid to the annular forward flow surface of the cup-shaped member; and at least one second passageway means extending in a straight line through the backsplash, to supply a portion of the coating fluid to a central portion of the front surface of the backsplash, the second means of passage an entrance in the conical projection, separated from the axis; a feed tube means having one end connected to a source of coating fluid and an opposite end positioned on the shaft adjacent to the projection, to supply coating fluid thereto; an annular shaped air cap, secured relative to one end of the housing and having an external surface extending from the housing to a peripheral portion of the bell; and an annular shaping air ring secured relative to the shaping air cap and having an inner surface in facing relationship with the outer surface of the air cap, and extending toward the peripheral portion of the bell; the outer surface of the air cap and the inner surface of the air ring cooperating to define a first annular chamber to receive a supply of pressurized air configuration, an annular formation of openings to receive said forming air from the first chamber, a second annular chamber to receive the shaping air from the first chamber, through the openings, and an open annular space, adjacent to the peripheral portion of the hood, the annular space receiving the shaping air from the second chamber and directing this shaping air towards the peripheral portion of the bell, in a thin uniform ring pattern or pattern.
