Air supply system for air springs and damper units for road vehicle suspension has motor driving air compressor and has 3/2-way valve supplying air to individual 2/2-way valves

摘要

The motor (M) drives a compressor (8) which draws air in through a suction line (9) from an air supply (10). Air may be supplied (28) to a filling valve (29) in each tire (30). The air supply for the air spring and damper units (3-6) flows (19) through a 3/2 way valve (31) to individual spring control valves (21-24). There is also a blow-off valve (25). Air may be supplied to a pressure air reservoir (7) via a second 3/2-way valve (32). The air circuit includes an air drier (12) and a bypass throttle (17).
