Abstract (en)

[origin: EP0478100A2] The invention relates to a shut-off member, in particular in the form of a pivotable shut-off flap and for large gas ducts, which contains a plate-like shut-off element capable of being pressed against a housing sealing seat. To be able to guarantee reliable and secure shutting-off of large gas ducts, the shut-off member forms, together with an additional cover, a chamber which is closed off gastightly with respect to the two spaces of the gas duct and the pressure of which is monitored and differs from the pressures prevailing in the two gas-duct spaces. <IMAGE>
