Abstract

Bei einer solchen Staudruckbegrenzung wird die Stirnfläche der in Geschlossenstellung befindlichen Drosselklappe (2) an einer Stelle von einer Ventilbohrung (8) überbrückt, in der ein Ventilkörper (10) verschiebbar ist, der von einer Feder (17) beaufschlagt ist. Dabei ist es erwünscht, wenn das Sicherungsventil mit größerer Zuverlässigkeit bei Überschreiten der oberen Staudruckgrenze angepaßt an das Ausmaß des Uberschreitens anspricht. Dies ist erreicht, indem zwischen der in Geschlossenstellung befindlichen Drosselklappe (2) und dem in Schließstellung befindlichen Ventilkörper (10) ein schmaler Spalt (19) vorhanden ist und die Kennlinie der Feder (17) unter einem Verhältnis Federkraft (N) : Federweg (mm) von 1,5 - 2,5 : 1 ansteigt. Es ist die Sogwirkung des durchströmenden Gases auf den Ventilkörper bei der Festlegung der Federkennlinie berücksichtigt. With such a dynamic pressure limitation, the end face of the in Throttle valve (2) in the closed position bridged at one point by a valve bore (8) in which a The valve body (10) is displaceable by a spring (17) is acted upon. It is desirable if the safety valve with greater reliability when the upper one is exceeded Dynamic pressure limit adapted to the extent of exceeding. This is achieved by switching between the in Throttle valve (2) and the position in The valve body (10) is in a closed position Gap (19) is present and the characteristic of the spring (17) under one Ratio of spring force (N): spring travel (mm) from 1.5 - 2.5 : 1 increases. It is the suction effect of the gas flowing through the Valve body when determining the spring characteristic considered.
