Compressed air supply system for operating air suspension system of e.g. sport utility vehicle, has throttle whose nominal size is adjustable by drive, where differential pressure exists between compressed air connection part and air dryer

摘要

The system (10) has a pneumatic main pipe (60) provided between a compressed air supply (1) and a compressed air connection part (2) and comprising an air dryer (61) and a throttle (62). A vent line (70) is provided between the compressed air connection part and an exhaust connection part (3). A nominal size of the throttle is adjustable by a differential pressure-regulated pneumatic drive (44), where the differential pressure exists between a compressed air supply connection part (52) and the compressed air connection part or between the compressed air connection part and the air dryer. Independent claims are also included for the following: (1) a pneumatic system (2) a method for operating a pneumatic system.
