Abstract

Regelbare Kühlmittelpumpe, bei welcher jede Leitschaufel (8) drei Achszapfen (9,10,11) aufweist, von denen sich ein erster und zweiter Achszapfen (9,10) im rechten Winkel zu je einer der beiden Längsseiten (12) der Leitschaufeln (8) erstreckt, die ersten und zweiten Achszapfen (9,10) im Bereich einer Außenkante (13) der Leitschaufel (8) angeordnet sind, wobei die Leitschaufel (8) im Pumpenkopf (4) über die ersten und zweiten Achszapfen (9,10) drehbar gelagert ist, und ein dritter, parallel zum ersten und zweiten Achszapfen (9,10) angeordneter Achszapfen (11) im von der Drehachse entfernten Bereich der Leitschaufel (8) angeordnet ist und in eine Nut oder ein Langloch (22) eines Verstellrings (23) ragt, der über den Distanzring (19) drehbar im Pumpenkopf (4) angeordnet ist, wobei die Nut oder das Langloch (22) eine radiale und eine tangentiale Komponente (r,t) aufweist.
Durch diese Erfindung können deutlich kleinere Steller zur Ansteuerung des Verstellrings verwendet werden.

Figure imgaf001
A controllable coolant pump, in which each vane (8) has three stub axles (9, 10, 11), of which a first and a second stub axle (9, 10) are at right angles to one of the two longitudinal sides (12) of the stator vanes (8, 8) ), the first and second stub axles (9, 10) being disposed in the region of an outer edge (13) of the vane (8), the vane (8) being located in the pump head (4) via the first and second stub axles (9, 10). is rotatably mounted, and a third, parallel to the first and second journal (9,10) arranged axle journal (11) in the remote from the axis of rotation of the guide vane (8) is arranged and in a groove or a slot (22) of an adjusting ring ( 23) which is rotatably arranged in the pump head (4) via the spacer ring (19), wherein the groove or slot (22) has a radial and a tangential component (r, t).
By this invention significantly smaller actuator can be used to control the adjusting ring.
