Abstract
The invention relates to a pneumatic open- and closed-loop control apparatus () for flows of pressure fluid, having one inlet conduit (), two outlet conduits (), and one venting conduit (), and also having a valve piston () mediating between these conduits and mounted in a valve chamber (), and to a method for open- and closed-loop control of flows of pressure fluid. It is proposed that by means of a pneumatically driven valve piston (), with a predeterminable time constant, one outlet conduit () each of the pneumatic open- and closed-loop control apparatus () is connected to the single inlet conduit (), while the other outlet conduit is simultaneously connected to the venting conduit ().
