Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Rückschlagventil, insbesondere für eine Kraftstoffhochdruckpumpe, nach der Gattung des Anspruchs 1.The invention relates to a check valve, in particular for a high-pressure fuel pump, according to the preamble of claim 1.
Ein solches Rückschlagventil für eine Kraftstoffhochdruckpumpe ist durch die
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Rückschlagventil mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass dieses einfach und kostengünstig herstellbar ist, da der Kopf des Ventilglieds als Kugel ausgebildet ist, wobei derartige Kugeln mit unterschiedlichen Durchmessern und hoher Genauigkeit am Markt leicht verfübar sind, beispielsweise für die Verwendung in Kugellagern. Die Verbindung des Kopfs mit dem Schaft ist auf einfache Weise herstellbar, beispielsweise mittels Schweißen.The check valve according to the invention with the features of claim 1 has the advantage that this is simple and inexpensive to produce, since the head of the valve member is designed as a ball, such balls with different diameters and high accuracy in the market are readily available, for example for Use in ball bearings. The connection of the head to the shaft can be produced in a simple manner, for example by means of welding.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Rückschlagventils angegeben. Durch die Ausbildung gemäß Anspruch 3 wird ein geringes Gewicht des Ventilglieds bei geringen Materialkosten erreicht. Die Ausbildung gemäß Anspruch 4 ermöglicht eine hohe Elastizität des Schafts des Ventilglieds, wodurch die Befestigung des Stützelements gemäß Anspruch 5 erleichtert wird. Die Ausbildung gemäß Anspruch 6 ermöglicht eine sichere Führung des Ventilglieds im Ventilgehäuse. Die Ausbildung gemäß Anspruch 7 ermöglicht auf einfache Weise eine Verbindung des Raums, in dem die Ventilfeder angeordnet ist, mit einem Zulauf des Rückschlagventils.In the dependent claims advantageous refinements and developments of the check valve according to the invention are given. Due to the construction according to claim 3, a low weight of the valve member is achieved at low material costs. The embodiment according to
