Grooved ring or sealing sleeve for separating pressure chamber, especially in vehicle hydraulic brakes or couplings - has basic body, and sealing lip extending to inner and or outer sealing surface

摘要

The part cross section of the sealing lip (2) decreases from preferably one point (3) starting in a peripheral direction to both sides continuously up to preferably a point (4) facing opposite by 180 degrees. The part cross section is reduced to up to half its original thickness. The inner envelope circle of the inner sealing lip eccentrically displaced in relation to the sealing lip`s outer envelope circle. The extent of the eccentric displacement amounts to half the sealing lip`s thickness. ADVANTAGE - The grooves ring or sealing sleeve exerts a subsequent suction action dispensing with a valve.
