- the further pressure regulator 56 in the second Pressure line path also causes, however, that in the pressure chamber 14 at If the pressure drops below the setpoint, the setpoint is immediately restored becomes.
- the second compressed air path contains between the valve assembly 62 and the Pressure chamber 14 of the pressure element 2 an open-close valve 64. This is closed when the compressed air from the Compressed air storage space 30 is conveyed into the pressure space 14 and prevented a escape of this compressed air via the valve arrangement 62 and / or through the pressure regulator 56 of the second compressed air path.
- the on-off valve 64 is only open, for example, only a fraction of a second later after the Pressure of the compressed air storage space 30 relaxes in the pressure space 14 has, to a pressure value which is essentially that of the pressure regulator 56 of the second compressed air path corresponds to the compressed air value.
- the on-off valve 64 by the Use another valve assembly 62, which the fulfills the same function, for example the same valve arrangement as that Valve arrangement 52 for controlling the Control piston 46.
- the Pressure regulator 36 in the first compressed air path is not a fixed one Pressure regulator, but a variably adjustable pressure regulator, then the Complete pneumatic circuit for different sized pressure rooms 14 can be used, for example for pressure rooms 14 of different lengths correspondingly different length cylinders with one to be cleaned Surface 8.
