    摘要： An air management system includes a pressurized air source (44). A manifold block (28) is coupled to the pressurized air source and includes a plurality of suspension valves (34,35) in fluid communication with the pressurized air source for controlling air flow to and from a plurality of air springs (22,24). An accumulator (82) is coupled to the manifold block for storing air. An accumulator valve (84) is in fluid communication with the plurality of suspension valves and the accumulator to allow exhausted air from the plurality of air springs into the accumulator. An electronic control unit (51) is electrically coupled to the plurality of suspension valves and the accumulator valve for controlling a sequence of operating the accumulator valve and the plurality of suspension valves to provide enhanced exhaust flow from the plurality of air springs to maintain the vehicle in a level orientation while lowering the vehicle.

    摘要： The invention relates to a leveling valve (101) for discharging and supplying air from and to a plurality of utilization elements (205 a,b), in particular pneumatic suspension bellows, the leveling valve (101) comprising a valve arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3) and said utilization elements (205 a,b), and a supply port (1) in fluid communication with the valve arrangement (103) and the source (207) of pressurized air.
    In particular, the invention suggests that a check valve (5) is mounted upstream of the valve arrangement (103), the check valve (5) being configured to allow fluid flow from the supply port (1) towards the valve arrangement (103) and to block fluid flow from the valve arrangement (103) through the supply port (1).

    摘要： An air suspension device includes an exterior compressed air source (9) that is mounted on a pressure accumulation tank (50) to supply compressed air, and a control unit (ECU) that controls a compressor device (CMP) to boost air pressure within the pressure accumulation tank (50) to fill an air spring device (A1, A2, A3, A4) with the compressed air, the control unit (ECU) controlling first and second inlet and outlet on-off valves (71, 72), first and second tank on-off valves (81, 82), and control valve (61, 62, 63, 64) to supply at least compressed air within the air spring device (A1, A2, A3, A4) to the pressure accumulation tank (50) when a pressure level of air within the air spring device (A1, A2, A3, A4) comes to be greater than a predetermined pressure level, or when a vehicle height value comes to be greater than a predetermined value.
