SEALING SYSTEM AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a seal for high pressure applications, in which a static and a dynamic sealing portion are separated from each other by a material thin point in such a manner that plastic flowing through the thin point is suppressed even if one of the two sealing portions is acted upon under high pressure as far as elastic compression.

主权项

1. A sealing system configured to seal a housing, the housing having a pressurizable stroke space in relation to a movable rod, the pressurizable stroke space is formed about an axis, the sealing system comprising a seal including:
a) a first dynamic sealing portion configured to seal between the seal and the rod, and b) a second static sealing portion configured to seal between the seal and the housing, c) the first and the second sealing portions formed integrally with each other, d) the first sealing portion merges via a material thin point into the second sealing portion to suppress a flow of a sealing material from the second sealing portion into the first sealing portion when pressurized.
