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 5):
The pneumatic valve drive as claimed in  claim 1 , further comprising at least one switching valve for swapping the pressure source that is connected to the respective cylinder cavity.
