Level regulation valve unit

The level-regulating valve unit (8) has a supply terminal (6,7) and an electrical connector (17,18), through which a control signal is transmitted for a purely electrical level control, where an electrically controlled or pilot operated valve and integrated distributor are provided. A pneumatic connector is connected with the integrated distributor for air bags, where air pressure level is electrically controlled by the level-regulating valve unit. An independent claim is included for an air-suspension system with lifting and lowering valve unit.
