Abstract (en)

The coolant and/or lubrication circuit, for an internal combustion motor, has a pump which is operated by an electromotor wh is controlled by a value from a constant control action. The pump is operated in relation to a nominal control value, either to stopped at times or simply operated at a lower power rating. A sensor sets the motor speed. The sensor can register wetness at a surface, for a fuel pump, and the adjustment can be to the paddle angle or height at a water pump to set the vol. of coolant impelled into the circuit.

Abstract (de)

Es wird eine Kühl- und/oder Schmiermittelfördereinrichtung zur Schmierölförderung oder Kühlwasserumwälzung in Brennkraftmaschinen beschrieben. Diese Pumpe ist durch einen in Abhängigkeit von einer Regelgröße einer stetigen Regelung steuerbaren Elektromotor antreibbar. Bezogen auf einen Regelsollwert kann die Pumpe durch die Regelung entweder zeitweise stillgesetzt oder lediglich so betrieben werden, dass sie mit entsprechend verminderter Leistung arbeitet.
