Abstract

A valve includes a housing having an inlet (3), an outlet (1) and a movable sealing member (2) which allows the inlet (3) and the outlet (1) to be connected in fluid communication with each other, the sealing member (2) having associated therewith effective areas (4b) to which pressure can be applied, and sealing areas (4), and the sealing member (2) further having associated therewith a sealing seat (4a) for sealing the inlet (3) from the outlet (1). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member (2) has associated therewith a conduit (2a) by which the inlet (3) and the outlet (1) can be connected in fluid communication with each other when the sealing member (2) rests on the sealing seat (4a).
