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 1):
A pneumatic valve drive for a valve, comprising a pneumatic cylinder having at least one piston that is mounted so as to be displaceable in the pneumatic cylinder, and having at least two cylinder cavities that are disposed at mutually opposite sides of the piston, each of the cylinder cavities is connected in each case to at least one pressure source in order for the respective cylinder cavity to be impinged with pressure, one of the pressure sources is a constant pressure source for impinging the cylinder cavity that is disposed on one of the sides of the piston with a constant pressure, and another of the pressure sources is a regulated pressure source for impinging the cylinder cavity that is disposed on an opposite side of the piston with a variably regulatable pressure.
