Abstract

L'invention concerne un dispositif d'étanchéité d'une tige de piston. Ledit dispositif est du type dans lequel une huile est appliquée du côté 5 basse pression et qui est utilisée pour empêcher l'échappement du gaz haute pression entre la surface de la tige 6 de piston et une surface environnante d'une garniture 12 en matière plastique qui présente un prolongement tubulaire 15 de diamètre interne légèrement croissant en direction du côté 4 haute pression. La garniture 12 est poussée contre la surface de la tige de piston mais le prolongement tubulaire 15 n'est pas influencé par la force exercée radialement sur la garniture 12. Application aux moteurs à gaz chaud.
