Compressed air supply installation and pneumatic system

A pneumatic system, comprising:

• a compressed air supply installation for operating an air suspension installation of a vehicle, the compressed air supply installation comprising:
• an air supply configured to supply air;
• an air compressor;
• a bleeding line, comprising:
• a bleeding valve arrangement in the form of a controllable solenoid valve arrangement comprising a magnetic part and a pneumatic part actuatable directly via the magnetic part, and
• a bleeding port for bleeding air;
• a compressed air supply line, comprising:
• an air dryer, and
• a compressed air port for supplying the pneumatic installation with compressed air;
• and
• the air suspension installation of the vehicle,
• wherein, in an unactivated state of the magnetic part of the solenoid valve arrangement, the pneumatic part of the solenoid valve arrangement is open in the bleeding line between a pressure-side valve port of the bleeding valve arrangement and a bleeding-side valve port of the bleeding valve arrangement.

A method for operating an air suspension installation of a vehicle via a compressed air supply installation, the method comprising:

• supplying a compressor with air via an air supply;
• supplying the air suspension installation of the vehicle with compressed air via a compressed air supply line between the air compressor and a compressed air port, the compressed air supply line including an air dryer;
• draining air from the air suspension installation of the vehicle via a bleeding line between the compressed air supply line and a bleeding port, the bleeding line comprising a bleeding valve arrangement in the form of a controllable solenoid valve arrangement comprising a magnetic part and a pneumatic part actuatable directly via the magnetic part,
• wherein, in an unactivated state of the magnetic part of the solenoid valve arrangement, the pneumatic part of the solenoid valve arrangement is open in the bleeding line between a pressure-side valve port of the bleeding valve arrangement and a bleeding-side valve port of the bleeding valve arrangement.
