Abstract:
A pneumatic valve drive ( 1 ) for a valve ( 2 ), in particular for a vacuum valve, which has at least one pneumatic cylinder ( 3 ) with at least one piston ( 4 ) that is movably mounted in the pneumatic cylinder ( 3 ) and at least two cylinder cavities ( 5, 6 ) arranged on opposite sides of the piston ( 4 ). Each cylinder cavity ( 5, 6 ) is connected to at least one pressure source for applying pressure to each cylinder cavity ( 5, 6 ). One of the pressure sources is a constant pressure source ( 7 ) for applying a constant pressure to the cylinder cavity ( 5 ) arranged on one of the sides of the piston, and one of the other pressure sources is a regulated pressure source ( 8 ) for applying a variably regulatable pressure to the cylinder cavity ( 6 ) arranged on the opposite side of the piston ( 4 ).

Claim (Index 4):
The pneumatic valve drive as claimed in  claim 3 , wherein the system pressure input is connected by way of a pressure reducer to the cylinder cavity that is disposed on one of the sides of the piston in order for the constant pressure source to be configured, or the system pressure input for configuring the regulated pressure source is connected at least by way of a pressure regulator valve to the cylinder cavity that is disposed on the opposite side of the piston.
