Abstract

Kühlmittelpumpe für die Förderung eines Kühlmittels in einem Kühlmittelkreis einer Brennkraftmaschine, die Kühlmittelpumpe umfassend:
a) ein Gehäuse (1),
b) eine vom Gehäuse (1) drehbar gelagerte Antriebswelle (4) für einen Drehantrieb vorzugsweise direkt durch die Brennkraftmaschine,
c) ein von der Antriebswelle (4) drehantreibbares, vorzugsweise mit der Antriebswelle (4) drehfest verbundenes Radialförderrad (2) für die Förderung des Kühlmittels aus einem radial innen liegenden Einströmbereich (5) in einen radial weiter außen liegenden Ausströmbereich (6),
d) eine mittels Steuerfluid relativ zu dem Gehäuse (1) in unterschiedliche Positionen verstellbare Stellstruktur (10) zur Verstellung einer das Fördervolumen der Pumpe bei gegebener Drehzahl beeinflussenden Strömungsgeometrie wie etwa eines Strömungsquerschnitts oder Strömungsverlaufs auf dem den Einströmbereich (5), das Radialförderrad (2) und den Ausströmbereich (6) umfassenden Strömungsweg des Kühlmittels,
e) ein Steuerventil (7) zur Einstellung eines die Position der Stellstruktur (10) bestimmenden Drucks oder Volumenstroms des vom Kühlmittel gebildeten Steuerfluids,
f) und zusätzlich zum Radialförderrad (2) eine Servopumpe (20; 50) für die Förderung des Steuerfluids zum Steuerventil (7),
dadurch gekennzeichnet, dass
g) die Servopumpe (20; 50) eine von der Antriebswelle (4) drehantreibbare Rotationspumpe mit wenigstens einem drehantreibbaren Servopumpenrad (21; 51, 52) ist.

Coolant pump for the delivery of a coolant in a coolant circuit of an internal combustion engine, the coolant pump comprising:
a) a housing (1),
b) one of the housing (1) rotatably mounted drive shaft (4) for a rotary drive, preferably directly by the internal combustion engine,
c) one of the drive shaft (4) rotatably driven, preferably with the drive shaft (4) rotatably connected Radialförderrad (2) for conveying the coolant from a radially inner inflow region (5) in a radially further outflow region (6),
d) a by means of control fluid relative to the housing (1) adjustable in different positions actuator structure (10) for adjusting a flow of the pump at a given speed influencing flow geometry such as a flow cross-section or flow on the inflow (5), the Radialförderrad (2 ) and the outflow area (6) comprising the flow path of the coolant,
e) a control valve (7) for setting a pressure or volume flow of the control fluid formed by the coolant, which determines the position of the actuating structure (10),
f) and in addition to the radial impeller (2) a servo pump (20; 50) for conveying the control fluid to the control valve (7),
characterized in that
g) the servo pump (20; 50) is a rotary pump rotatably driven by the drive shaft (4) with at least one rotatably driven servo pump wheel (21; 51,52).
