Derartige Druckbegrenzungsventile haben die Aufgabe, eine Druckregelung in einem Kraftstoffversorgungskreislauf einer Verbrennungskraftmaschine zu übernehmen. Über das Druckbegrenzungsventil wird der über ein Fördermittel, beispielsweise eine Kraftstoffpumpe, in den Versorgungskreislauf aufgebauter Druck begrenzt. Infolge von Druckschwankungen in dem Kraftstoffsystem kann es zu stark beschleunigten Bewegungen eines Ventilkolbens des Druckbegrenzungsventils kommen. Der Ventilkolben kann hierdurch gegen ein Ventilgehäuse schlagen und zu unerwünschten Geräuschentwicklungen führen.valves or spring elements of the generic type are known. These For example, in pressure relief valves for fuel supply systems for motor vehicles used. Such pressure relief valves have the task a pressure control in a fuel supply circuit of a Internal combustion engine to take over. About the Pressure relief valve is the over a funding, For example, a fuel pump in the supply circuit limited pressure built up. As a result of pressure fluctuations in the Fuel system can cause greatly accelerated movements of one Valve piston of the pressure relief valve come. The valve piston can thereby beat against a valve housing and undesirable noise generation to lead.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Ventil und ein Federelement der gattungsgemäßen Art zu schaffen, mit denen in einfacher Weise eine Dämpfung von Ventilöffnungs- beziehungsweise Ventilschließbewegungen möglich ist.Of the Invention is therefore based on the object, a valve and a spring element of the generic type with which a damping of valve opening in a simple manner or valve closing movements possible is.
