Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Förderleistung der Kühlmittelpumpe mit Hilfe des Betätigungsorgans des integrierten Stellventil veränderbar ist.These The object is achieved according to the invention that the flow rate of the coolant pump with Help of the actuator of the integrated control valve is changeable.
Der Erfindung liegt dabei der Gedanke zugrunde, dass sich zur Veränderung der Ventilstellung des Stellventils benötigte Betätigungsorgan auch zur Veränderung der Förderleistung der Kühlmittelpumpe nutzen lässt.Of the Invention is based on the idea that to change the valve position of the control valve required actuator also for changing the delivery rate of the coolant pump use.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass zwei aufeinanderfolgende Betätigungsvorgänge des Betätigungsorgans zuerst eine Veränderung der Förderleistung der Kühlmittelpumpe und dann eine Veränderung einer Ventilstellung des Stellventils bewirken, wobei zweckmäßig vor dem ersten Betätigungsvorgang ein Hindurchtritt von Kühlmittel durch die Kühlmittelpumpe blockiert und nach dem ersten Betätigungsvorgang freigegeben ist. Auf diese Weise kann nach einem Kaltstart der Brennkraftmaschine zur Verkürzung der Warmlaufphase für stehendes Kühlmittel in der Brennkraftmaschine gesorgt werden, bis sich das Kühlmittel auf eine gewünschte Temperatur erwärmt hat. Nach der Freigabe des Kühlmittelstroms durch die Kühlmittelpumpe kann dann durch die Veränderung der Ventilstellung des Stellventils eine Steuerung oder Regelung der Strömungsmenge durch die Kühlmittelpumpe bzw. durch verschiedene Teilzweige des Kühlkreislaufs vorgenommen werden, um dadurch eine gewünschte Solltemperatur im Kühlkreislauf bzw. in dessen Teilzweigen einzustellen.

This way you can after a cold start of the engine for shortening the warm-up phase for stagnant coolant in the internal combustion engine are taken care of until the coolant has heated to a desired temperature. To the release of the coolant flow through the coolant pump can then by changing the valve position of the Control valve, a control or regulation of the flow rate through the coolant pump or through various sub-branches the cooling circuit are made, thereby a desired Target temperature in the cooling circuit or in its sub-branches adjust. Alternatively, however, it may also be provided that a single operation at the same time a Change in the delivery rate of the coolant pump and a change of a valve position of the control valve causes.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung wird das Betätigungsorgan von einer drehbaren Abtriebswelle eines Stellmotors gebildet, wobei das Verdrehen der Abtriebswelle über einen vorgegebenen ersten Drehwinkel aus einer Ausgangsstellung eine Veränderung der Förderleistung der Kühlmittelpumpe bewirkt, während das Verdrehen der Abtriebswelle über den vorgegebenen ersten Drehwinkel hinaus, oder alternativ in eine Zwischenstellung zwischen der Ausgangsstellung und dem vorgegebenen ersten Drehwinkel, eine Veränderung der Ventilstellung des Stellventils bewirkt.According to one Another preferred embodiment of the invention, the actuator of formed of a rotatable output shaft of a servomotor, wherein the rotation of the output shaft over a predetermined first rotation angle from a starting position a change the capacity of the coolant pump causes while turning the output shaft over the predetermined first rotation angle addition, or alternatively in an intermediate position between the initial position and the predetermined first rotation angle, causes a change in the valve position of the control valve.
Zur Veränderung der Förderleistung der Kühlmittelpumpe dient vorzugsweise ein in axialer Richtung eines Pumpenrades der Kühlmittelpumpe beweglicher Schieber, der zweckmäßig als Schiebertopf ausgebildet und drehfest und axial verschiebbar im Pumpengehäuse montiert ist und der durch Betätigung des Betätigungsorgans zwischen zwei Endstellungen verfahrbar ist, wobei er in einer ersten Endstellung das Pumpenrad entlang seines Umfangs umgibt und den Hindurchtritt von Kühlmittel durch die Kühlmittelpumpe verhindert, während er in einer zweiten Endstellung vom Pumpenrad zurückgezogen ist und den Hindurchtritt von Kühlmittel durch die Kühlmittelpumpe gestattet. Der Schieber bleibt beim zweiten, zur Veränderung der Ventilstellung des Stellventils dienenden Betätigungsvorgang des Betätigungsorgans zweckmäßig in der zweiten Endstellung stehen.to Change in the delivery rate of the coolant pump is preferably used in the axial direction of an impeller of Coolant pump movable slide, the appropriate designed as a sliding pot and rotatably and axially displaceable in Pump housing is mounted and by actuation the actuator between two end positions movable is, wherein it in a first end position along the impeller surrounds its periphery and the passage of coolant prevented by the coolant pump while he retracted from the impeller in a second end position is and the passage of coolant through the coolant pump allowed. The slider remains at the second, to change the valve position of the control valve serving actuating operation of the actuator expedient in the second end position stand.
Um die Abdichtung des Schiebers in der ersten Endstellung zu verbessern, taucht dieser vorteilhaft in dieser Stellung mit einem vorderen Rand in eine gegenüberliegende komplementäre Vertiefung im Pumpengehäuse ein.In order to improve the sealing of the slide in the first end position, this emerges advantageously in this position with a front edge in an opposite complementary recess in the pump housing a.
Das Stellventil kann mit Vorteil als Drehschieberventil ausgebildet sein, dessen Drehschieber zweckmäßig drehfest mit einer als Betätigungsorgan dienenden Abtriebswelle des Stellmotors verbunden ist.
