Abstract
An automatic level control device for vehicles is furnished with an electrically triggered shut-off valve (44). The shut-off valve (44) can be loaded with a pressure in closure direction corresponding to an air-suspension pressure. The force to be exerted by the electrical actuation device (23) for opening of the shut-off valve (44) is independent of the closure pressure loading the shut-off valve (44). The device components of the electrical actuation device (23) of the shut-off valve (44) can be furnished of small volume size and the passage cross-section of the shut-opff valve (44) can be formed of relatively large size. The device serves for automatic level control devices for vehicles.
