Abstract

Bei einer Einrichtung (1) zur Steuerung der aus einer Düse (14) ausströmenden Menge eines Mediums mit einer Förderpumpe (2) und einer Förderkammer (10) sind in die­ ser eine Steuerhülse (31) sowie ein mit dieser zusammen­ wirkender Steuerkolben (32) eingesetzt, die trieblich mit dem Ventilkörper (13) des der Pumpe (2) zugeordneten Auslaßventils und entgegen der Kraft einer Rückstellfe­ der (38) verschiebbar sind. Außerdem sind die Steuerhülse (31) und/oder der Steuerkolben (32) mit Drosselöffnungen (33) versehen, deren Durchgangsquerschnittsfläche zur Einstellung der jeweiligen, durch die Düse (14) abströmen­ den Menge des Mediums einstellbar und durch Relativver­ schiebungen des Steuerkolbens (32) gegenüber der Steuer­ hülse (31) in Abhängigkeit von der Lage des Ventilkörpers (13) des Auslaßventils (11) selbttätig veränderbar sind. In a device (1) for controlling the from a Nozzle (14) flowing out of a medium with a Delivery pump (2) and a delivery chamber (10) are in the water a control sleeve (31) and together with this acting control piston (32) used, the drive with the valve body (13) of the pump (2) assigned Exhaust valve and against the force of a Rückstellfe the (38) are displaceable. In addition, the control sleeve (31) and / or the control piston (32) with throttle openings (33) provided, the passage cross-sectional area to Adjust the respective flow through the nozzle (14) the amount of the medium adjustable and by Relativver shifts of the control piston (32) with respect to the tax sleeve (31) depending on the position of the valve body (13) of the outlet valve (11) can be changed automatically.

Dadurch ist es möglich, die abzugebende Menge in einem großen Bereich stufenlos einzustellen, ohne daß die Förder­ leistung der Pumpe (2) und/oder der Grad der Zerstäubung beeinträchtigt werden. Das überschüssige von der Pumpe (2) geförderte Medium wird hierbei nicht in den Vorratsbe­ hälter zurückgeführt, das Medium verbleibt vielmehr in der Pump- und/oder Förderkammer (6 bzw. 10). This makes it possible to dispense the quantity to be dispensed in one steplessly adjust large area without the conveyor performance of the pump (2) and / or the degree of atomization be affected. The excess from the pump (2) Funded medium is not in the storage tank container returned, the medium remains rather in the pumping and / or delivery chamber (6 or 10).
