Abstract

In a vacuum-tight closing valve for high differential pressures and large throughflow openings, in which one or more sealing plates (60, 61) compress the seals (79, 83) in such a way that vacuum-tight closure of the throughflow openings (64) in the housing (65) is achieved, vacuum-tight resilient elements (78, 82) which maintains the contact pressure are arranged between the sealing plate (61, 62) and the seal (79, 83). <IMAGE>
