Abstract

Die Erfindung betrifft eine über eine Riemenscheibe angetriebene regelbare Kühlmittelpumpe für Verbrennungsmotore.The invention relates to a controlled via a pulley controllable coolant pump for internal combustion engines.

Der Erfindung liegt die Aufgabe zugrunde, eine über eine Riemenscheibe angetriebene, regelbare Kühlmittelpumpe für Verbrennungsmotore zu entwickeln, welche die Nachteile des Standes der Technik vermeidet, sich durch einen hohen Wirkungsgrad, eine hohe Betriebssicherheit undThe invention has for its object to develop a driven via a pulley, controllable coolant pump for internal combustion engines, which avoids the disadvantages of the prior art, by a high efficiency, high reliability and

Zuverlässigkeit sowie einen minimalen Fertigungs- und Montageaufwand auszeichnet, eine aktive Steuerung der Kühlmittelfördermenge ermöglicht, um eine allmähliche optimale Erwärmung des Motors zu gewährleisten und um gleichzeitig nach der Erwärmung des Motors die Motortemperatur im Dauerbetrieb so zu beeinflussen, daß im gesamten Arbeitsbereich des Motors sowohl die Schadstoffemission wie auch die Reibungsverluste und der Kraftstoffverbrauch deutlich reduziert werden können.Reliability and minimal manufacturing and assembly costs, allows active control of the coolant flow rate to ensure a gradual optimum heating of the engine and at the same time to influence the engine temperature in continuous operation after the heating of the engine so that the entire working range of the engine Pollutant emission as well as the friction losses and fuel consumption can be significantly reduced.

Erfindungsgemäß zeichnet sich die regelbare Kühlmittelpumpe unter anderem dadurch aus, daß im Pumpengehäuse (1) ein Magnetgehäuse (14) mit einer Magnetspule (16) und ein mit einem Magnetankers (24) versehener, durch eine Druckfeder (28) belasteter Ventilschieber (21) angeordnet ist, dessen Außenzylinder (20) mit seinem Innendurchmesser den Außendurchmesser des Flügelrades (6) geringfügig überragt und der entlang der äußeren Breite des Flügelrades (6) so verschoben werden kann, daß in einer Endlagenstellung des Ventilschiebers (21) der Zufluss vom Flügelrad (6) in die Pumpenspirale (33) frei gegeben, und in der anderen Endlagenstellung des Ventilschiebers (21) der Zufluss vom Flügelrad (6) in die Pumpenspirale (33) versperrt ist.

Figure imgaf001
According to the invention, the controllable coolant pump is characterized, inter alia, by the pump housing (1) having a magnet housing (14) with a magnet coil (16) and a valve slide (21) loaded with a magnet armature (24) and loaded by a compression spring (28) is, the outer cylinder (20) with its inner diameter, the outer diameter of the impeller (6) slightly surmounted and along the outer width of the impeller (6) can be moved so that in an end position of the valve spool (21) the inflow from the impeller (6 ) in the pump coil (33) released, and in the other end position of the valve spool (21) the inflow of the impeller (6) is blocked in the pump spiral (33).
