Abstract
A compressed air supply device for operating a pneumatic installation comprises an air supply unit configured to supply air, an air compression unit configured to compress air, a bleeding line comprising a controllable solenoid valve arrangement, the solenoid valve arrangement having a magnetic part and a pneumatic part, and a bleeding port configured to bleed air. The device also comprises a compressed air supply line having an air drier and a compressed air port, the compressed air supply line being configured to supply the pneumatic installation with compressed air, wherein the pneumatic part is open when the magnetic part is not activated.
Claims51
A compressed air supply device for operating a pneumatic installation, comprising:
- an air supply unit configured to supply air;
- an air compression unit configured to compress air;
- a bleeding line comprising a controllable solenoid valve arrangement and a bleeding port configured to bleed air, the solenoid valve arrangement having a magnetic part and a pneumatic part;
- and
