Abstract
A sealing system which has an annular seal which is used for sealing between a first member and a second member and which has a base portion, from which there projects axially in the direction towards the second member a sealing lip which ends in an end-side sealing portion which abuts an annular sealing face of the second member in a sealing manner. The annular sealing face has a conical first sealing face portion and a second sealing face portion which adjoins it in a radially outward direction, wherein the portion is formed by the base face of an annular indentation of the second member. The sealing lip tapers in the direction towards the sealing portion thereof and in the position for use thereof is axially compressed by the action by means of the two members and at the same time curved radially inwards. The sealing system is in particular a component of a valve.
