Abstract

Cylindre comportant des éléments qui assurent à la fois une étanchéité statique et une étanchéité dynamique. Le carter 1 est subdivisé par le piston 3 en une chambre 4 de déblocage de frein et une chambre 5 du ressort 6. Le piston 3 est muni d'une tige de poussoir 7 avec une tête 8. La chambre 5 a un raccordement de décompression 9 et la chambre 4 un raccordement au fluide 10. Le joint il a une surface d'étanchéité dynamique 11a et une surface d'étanchéité statique 11b. Le joint 12 réalise une étanchéité dynamique et, avec l'arête 8a de la tête 8, une étanchéité statique. Les anneaux de guidage 15b et 17a/17b à étanchéité statique coopèrent avec les joints à étanchéité dynamique 16 18.Cylinder comprising elements which provide both static and dynamic sealing. The housing 1 is subdivided by the piston 3 into a brake release chamber 4 and a chamber 5 for the spring 6. The piston 3 is provided with a push rod 7 with a head 8. The chamber 5 has a pressure relief connection. 9 and the chamber 4 a connection to the fluid 10. The seal has a dynamic sealing surface 11a and a static sealing surface 11b. The seal 12 provides dynamic sealing and, with the edge 8a of the head 8, a static sealing. The statically sealed guide rings 15b and 17a / 17b cooperate with the dynamic seals 16 18.
