Abstract

Eine Kühlmittelpumpe für eine Fahrzeug-Brennkraft­ maschine weist ein in einem Gehäuse 1 angeordnetes, mit Radialschaufeln 15 versehenes Laufrad 3 auf, das mit der Antriebswelle 4 über ein Gewinde 7, 8 relativ drehbar und axial verschiebbar verbunden ist. Zwischen dem Laufrad 3 und der Antriebswelle 4 ist eine Torsionsfeder 9 angeordnet, die einer Drehung des Laufrades 3 relativ zur Antriebswelle 4 bis zu einem bestimmten Antriebsdrehmoment entgegenwirkt. Übersteigt das Antriebsdrehmoment infolge steigender Drehzahl diesen Wert, so kann sich das Laufrad 3 relativ zur Antriebswelle 4 verdrehen und es wird aufgrund des Gewindes 7, 8 axial verschoben, wobei sich der Spalt S zwischen den Radialschaufeln 15 und der Pumpengehäusewand 18 vergrößert und die Fördermenge bezogen auf die Drehzahl verringert wird. Dadurch wird eine verhältnismäßig große Förder­ menge bei niedrigen Drehzahlen und eine verhältnismäßig geringe Fördermenge bei hohen Drehzahlen erreicht. A coolant pump for a vehicle internal combustion engine machine has a arranged in a housing 1, impeller 3 provided with radial blades 15, with the drive shaft 4 via a thread 7, 8 is relatively rotatable and axially slidably connected. Is between the impeller 3 and the drive shaft 4 a torsion spring 9 arranged to cause rotation of the impeller 3 relative to the drive shaft 4 up to counteracts a certain drive torque. Exceeds the drive torque due to increasing Speed this value, the impeller 3 turn relative to the drive shaft 4 and it will axially shifted due to the thread 7, 8, wherein the gap S between the radial blades 15 and the pump housing wall 18 enlarged and the Delivery rate related to the speed reduced becomes. This makes a relatively large funding amount at low speeds and a proportionate low flow rate achieved at high speeds.
