Abstract: 1316223 Suspension levelling systems ROBERT BOSCH GmbH 19 April 1971 [20 March 1970] 24824/71 Heading B7D A closed-circuit pneumatic suspension levelling system for a motor vehicle includes a compressor 38 driven by an electric motor and housed in an air reservoir 42 together with solenoid-actuated air supply and release valves 10, 11 and 12, 13 controlled by levelling switches 7, 8, and a reservoir air-loss replenishing system comprising a replenishing valve and a two-step pressure switch 30 which establishes a replenishing system operating range between upper and lower reservoir pressure valves, and a control relay 41 operated by the pressure switch 30 for giving levelling operations priority over replenishing operations when the reservoir pressure is in the operating range. The levelling switches 7, 8 are associated through damping means 5<SP>1</SP>, 6<SP>1</SP> with axles 5, 6 suspended by air springs 1, 2, 3, 4. The pressure switch 30 has contacts 28, 28<SP>1</SP> and 29, 29<SP>1</SP> actuated by a spring-loaded piston 35. When the reservoir pressure exceeds six atmospheres the contacts 28, 28<SP>1</SP> are closed and the contacts 29, 29<SP>1</SP> are open as shown. If an axle is high the compressor motor is energized through a motor relay 40 so that air is drawn from the reservoir through a port 43 and delivered to a valve block 9 through a port 39, and the winding 20, 22 of the appropriate supply valve 10, 12 is energized so that the air is delivered to the air springs 1, 2 or 3, 4. If an axle is low the winding 21, 23 of the appropriate release valve 11, 13 is energized so that air is released from the air springs. When the reservoir pressure is between three and six atmospheres the contacts 29, 29<SP>1</SP> close so that the compressor motor is energized through the relay 40 and the winding 24 of the replenishing valve is energized through the control relay 41 whereupon the compressor draws atmospheric air through a port 26 and supplies the reservoir through the port 43. However, if one of the levelling switches 7, 8 closes the control relay 41 is opened so that the winding 24 is de-energized and the required levelling operation can take place. If the reservoir pressure falls below three atmospheres the contacts 28, 28<SP>1</SP> open so that no levelling operations can take place until sufficient reservoir pressure is restored.
