Abstract

Bei einer Anlage zum Beschichten von Werkstücken mit einer Flüssigkeit, bspw. zum elektrostatischen Lak­ kieren von Kraftfahrzeug-Karosserien in Fliessbandbe­ trieb, mit Zerstäubern für die Flüssigkeit, bei der ein Flüssigkeitsdruckregler zwischen einem Flüssigkeits­ wechsler und mindestens einem, an den Flüssigkeits­ wechsler angeschlossenen Zerstäuber angeordnet ist, wird ein druckluftgesteuerter Flüssigkeitsregler verwen­ det. An seiner Membran (48) ist an der der Beschich­ tungsflüssigkeitskammer zugewandten Seite eine ver­ dickte Platte (58) angebracht, die den Einlass (52) für die Beschichtungsflüssigkeit bei maximalem Luftdruck über­ deckt. Dadurch wird um die Platte in der Kammer ein ringförmiger Raum geschaffen. Eine Nut (64) in der Platte verbindet den Einlass mit dem ringförmigen Raum. In den Einlass (52) wird Spülflüssigkeit gegeben. Der Umfang der Kammer wird durch das Strömen der Spül­ flüssigkeit im ringförmigen Raum besonders gut gerei­ nigt. In a system for coating workpieces with a liquid, e.g. for electrostatic lac Kieren of motor vehicle bodies in assembly line powered, with atomizers for the liquid at which one Liquid pressure regulator between a liquid changer and at least one on the liquid connected atomizer is arranged, a compressed air controlled liquid regulator is used det. On its membrane (48) is the coating liquid side facing a ver Thick plate (58) attached, the inlet (52) for the Coating liquid at maximum air pressure above covers. This will turn around the plate in the chamber created an annular space. A groove (64) in the Plate connects the inlet to the annular space. Rinsing liquid is added to the inlet (52). The Circumference of the chamber is caused by the flow of the irrigation liquid in the ring-shaped space is particularly easy to handle nends.
