摘要:
The invention relates to a spray tool (10) having a source (20, 21) for liquid working medium, a source (22) for control medium and a plurality of spray modules (14). Each spray module (14) has at least one feed (18, 19) for liquid working medium and at least one feed (38) for control medium, and comprises at least one spray element (16) for discharging liquid working medium. The spray modules (14) are combined to form a plurality of spray circuits (K 1 , K 2 , ...), the supply of control medium to which can be controlled independently of the supply of control medium to the other spray circuits. At least one spray circuit (K 1 , K 2 , ...) is assigned a distributor unit (28) which has a plurality of connection points (24) for connecting lines (26) which are guided freely to the feeds (38) of the spray modules (14) belonging to this spray circuit.

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum dosierten Auftragen einer fluiden oder sprühfähigen Zubereitung auf die Körperoberfläche eines Anwenders, mit mehreren an unterschiedlichen Positionen angeordneten Verteilungselementen (ZD) für die gerichtete oder zumindest gebündelte Ausgabe der Zubereitung, und mit einer den Verteilungselementen (ZD) zugeordneten Steuerungseinrichtung (SPS), die die Verteilungselemente (ZD) im Sinne einer voreinstellbaren dosierten Abgabe der Zubereitung steuert. Für eine ultrafeine Zerstäubung und Vernebelung der Zubereitung bei minimalem Betriebsmittelverbrauch der Zubereitung ist ein Zerstäubungsmedium für den Transport der Zubereitung und für das Aufreissen des Flüssigkeitsstroms der Zubereitung in feinste Tropfen vorgesehen, wobei die mehreren Verteilungselemente (ZD) derart angeordnet sind, dass die Ausgabe der Zubereitung auf die Körperoberfläche des Anwenders mit einem vorbestimmten Vollkegelsprühbild mit optimalen Strahlwinkel (W) und Sprühweite (A) erfolgt.

A recirculating paint supply system supplies single or multiple paint coating to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits (102, 104) to supply paint to an improved spray gun (88). In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages (338) which provide for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.

The invention concerns a vehicular device for applying plant treatment agents, with a spraying device and at least one tank (24, 24') for the plant treatment agent and a separate tank for a diluent, and also with at least one metering device (32, 32') for injecting measured quantities of the treatment agent into mixing chambers (31, 31') for mixing with the diluent. The metering devices (32, 32') used in the invention inject the treatment agent into the mixing chambers (31, 31'), into which the diluent is pumped under constant-pressure control (30), only when a given output pressure is exceeded. For each group (6) of spray heads in the sprayer unit (11) and/or for each spraying agent, a reciprocating-piston pump (1) is provided as the metering device (32, 32'). The pumps (1) are driven via electromagnetic transductors (8) at constant piston speed and stroke, and their associated mixing chambers (31, 31') are located in the immediate vicinity of the spray nozzles (2, 3, 4, 5) of a particular group (6) of heads in the sprayer unit (11). The operating frequency of the reciprocating-piston pump (1) is controlled by frequency control of the electromagnetic transductor (8), as a function of the instantaneous speed of travel of the spraying device and the required output and concentration of the treatment agent, by means of a computing and control unit.
摘要:
A method and apparatus (10) for forming and dispensing a coating material formulation or solution containing a liquid coating composition and a fluid diluent such as a supercritical fluid comprises a supply (14) for the liquid coating composition, a supply (41) for the fluid diluent, a mixer (38) for combining the two components to form the coating material solution or formulation, and a control system (109) for monitoring a parameter of the formulation which can be correlated to the fluid diluent content and/or liquid coating composition content of the formulation, and for monitoring the pressure of the formulation at selected locations within the apparatus (10). The control system (109) is effective to open or close the supply of fluid diluent (41) and/or liquid coating composition (14) in accordance with variations in the formulation parameter which is being sensed, and in response to pressure changes within the apparatus (10), to maintain single or multiple phase coating material formulations, to account for changes in a parameter of the liquid coating composition and to ensure that the desired ratio of fluid diluent to liquid coating composition is maintained in the formulation which is supplied to coating dispensers (12) for deposition onto a substrate.

Bei einer Vorrichtung zum Ausbringen von Pflanzenschutzmitteln und dergleichen, mit einem Tank für Trägerfluid, z.B. Wasser, und einer Förderpumpe, die Trägerfluid aus diesem Tank durch eine Leitung pumpt, an der Spritzdüsen angeschlossen sind, und mit einer Dosierpumpe, die durch eine Verbindungsleitung an einen Präparatbehälter angeschlossen und von dem von der Förderpumpe gelieferten Trägerfluid angetrieben ist, wird zur Vermeidung einer aufwendigen Steuereinrichtung für die Konzentration des Präparats im Trägerfluid und zur Erzielung einer zuverlässigen und genauen Dosierung die Dosierpumpe (5) mit der Förderpumpe (2) in Reihe geschaltet, so daß die Dosierpumpe (5) von dem gesamten, durch die Leitung (3) strömenden Trägerfluid durchströmt wird, wobei das Trägerfluid ein Antriebselement (12) in der Dosierpumpe (5) antreibt, das wiederum eine Dosiereinrichtung (13, 14) antreibt, die mit der zum Präparatbehälter (11) führenden Verbindungsleitung (10) verbunden und mit einer Einstelleinrichtung (15) für die Konzentration des Präparats versehen ist.
