Compressed air supply device

摘要

The device has a flanged joint (18) providing electrical and pneumatic interfaces (20, 22) between an electronic air conditioning system (12) and a pneumatic suspension module (16). The module has two pneumatically controllable aerating and deaerating -2/2- valves (24, 26) to aerate and deaerate a common inlet joint of two pneumatically controllable supply-2/2-valves (30, 32). A pressure sensor is attached to the common inlet joint. An electrically actuatable 3/2-valve is provided to control the aerating and deaerating valves.
