Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Pumpe, insbesondere für eine Kraftstoffeinspritzeinrichtung für eine Brennkraftmaschine nach der Gattung des Anspruchs 1.The invention is based on one Pump, especially for a fuel injection device for an internal combustion engine the type of claim 1.
Eine solche Pumpe ist durch die
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Pumpe mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, daß deren Zusammenbau durch die am Stützelement fixierte Ventilfeder vereinfacht ist. Die Ventilfeder und das Stützelement können dabei auesserhalb der Pumpe miteinander verbunden werden und anschließend als Verbund in der Pumpe montiert werden.The pump according to the invention with the features according to claim 1 has in contrast the advantage that their Assembly by the on the support element fixed valve spring is simplified. The valve spring and the support element can are connected outside of the pump and then as Can be assembled in the pump.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Pumpe angegeben.In the dependent claims are advantageous refinements and developments of the pump according to the invention specified.
