Abstract

  • 2.1 Tassenstößel mit Membranen aus elastomeren Werkstoffen verlangen dauerhafte, sichere Dichtstellen für einen Temperaturbereich von minus 40° bis 180°C. Klemmkonstruktionen bisher bekannter Bauarten sind nicht dauerhaltbar. Mit der Erfindung soll eine verbesserte Abdichtung für Tassenstößel geschaffen werden. 2.1 tappets with membranes made of elastomeric materials require permanent, secure sealing points for you Temperature range from minus 40 ° to 180 ° C. Clamp structures of previously known types are not durable. The invention aims at an improved Sealing for cup tappets can be created.
  • 2.2 Die Membran ist mit mindestens zwei ringförmigen Vorsprüngen (6, 7) an ihrem wulstförmigen Endbereich (8) ausgebildet. Darüber hinaus sind Freiräume (10, 11) vorgesehen, in welche der Elastomerwerkstoff einfließen kann. 2.2 The membrane is ring-shaped with at least two Projections (6, 7) on their bead-shaped end region (8) educated. In addition, there are free spaces (10, 11) provided, into which the elastomer material flow can.
  • 2.3 Der verbesserte Tassenstößel eignet sich insbesondere für den Einsatz in Brennkraftmaschinen mit hoher Drehzahl. 2.3 The improved tappet is particularly suitable for use in internal combustion engines at high speed.
