Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Pumpe, insbesondere Kraftstoffhochdruckpumpe, nach der Gattung des Anspruchs 1.The invention relates to a pump, in particular high-pressure fuel pump, according to the preamble of claim 1.
Eine solche Pumpe in Form einer Kraftstoffhochdruckpumpe ist durch die
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Pumpe mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass durch den Nocken und die Rolle stabilisierende Kräfte erzeugt werden, durch die eine Verdrehung des Stützelements mit der Rolle verhindert wird, so dass Schäden an der Pumpe vermieden werden können.The pump according to the invention with the features according to claim 1 has the advantage that stabilizing forces are generated by the cam and the roller, by which a rotation of the support member is prevented with the roller, so that damage to the pump can be avoided.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Pumpe angegeben. Durch die Ausbildung gemäß Anspruch 6 werden zu hohe Flächenpressungen zwischen den Randbereichen der Rolle und der Nockenlaufbahn vermieden.In the dependent claims advantageous refinements and developments of the pump according to the invention are given. Due to the design according to claim 6 too high surface pressures between the edge regions of the roller and the cam track are avoided.
