Abstract
Method of operating a valve (1) which connects openings (2, 3) of at least two chambers (4, 5) to one another and, for closing the openings (2, 3) of each of the chambers (4, 5), has at least one dedicated closure member (6, 7), wherein for opening one of the openings (2, 3), the chamber (4, 5) assigned to said opening (2, 3) has generated in it a positive pressure which is higher than a current pressure in the valve-housing interior (8), wherein, by virtue of this positive pressure, the closure member (6, 7) assigned to said opening is raised up from the valve seat (10, 11) assigned to said opening (2, 3) and then, through this opening (2, 3), pressure equalization is carried out between the valve-housing interior (8) and the chamber (4, 5) assigned to said opening (2, 3). (FIG. 1)
