    • The invention relates to a compressed air supply system for operating a pneumatic system, in particular an air suspension system of a motor vehicle, comprising: a compressed air feed (1); a compressed air connection (2) to the pneumatic system (90); a ventilation connection (3) to the surroundings; a pneumatic main conduit (60), which has an air drier (61) between the compressed air feed (1) and the compressed air connection (2); a ventilation conduit (70) between the compressed air connection (1) and the ventilation connection (3); a magnetic valve arrangement (80) comprising a control valve (81, 81', 82") for controlling a ventilation valve (71), the control valve (81, 81', 82") being connected to a control valve connection (X2, Y2) in a pneumatic control conduit (110) that is connected to a pressure control connection (71S) of the ventilation valve (71), and the ventilation valve (71) being connected to a ventilation valve connection (X1, Y1) in the ventilation conduit (70). According to the invention, a pressure-maintaining, pneumatic device (120) is connected to the, in particular in the pneumatic control conduit (110) and is designed to maintain the pressure control connection (71S) under control pressure when the ventilation valve connection (X1, Y1) of the ventilation valve (71) in the ventilation conduit (70) is open, independently of pressure in the ventilation conduit (70) and/or the pneumatic main conduit (60).

    • The invention relates to a pneumatic suspension system (1a, 1b, 1e) of a motor vehicle, comprising a plurality of spring bellows (23, 24) that are associated with the pneumatic springs of at least one vehicle axle, can be connected by means of the respective linking leads (29, 30) that are each provided with a level control valve (25, 26) to a main pressure line (22), and can be shut off with respect to same, wherein the main pressure line (22) can be connected by means of at least one associated valve (3, 6, 10, 34) alternately to a compressed air source and a compressed air sink and can be shut off with respect to same. According to the invention, in order to set different flow rates of the air mass flow in a simple and cost-effective manner when air is supplied to and removed from the spring bellows (23, 24), the spring bellows (23; 24) of the pneumatic springs arranged at least on a vehicle axle or on a vehicle side can be respectively connected to the main pressure line (22) in parallel with the first connecting lines (29; 30) at least by means of a second connecting line (31; 32) provided with a second level control valve (27; 28) and can be shut off with respect to said main pressure line. The second level control valves (27; 28) of the relevant spring bellows (23; 24) each have nozzle cross-sectional surfaces (NW
      X = NW
      Y ) of the same size as the first level control valve (25; 26), and a choke (51; 52) is connected downstream of each of the second level control valves (27; 28) in the ventilation direction, the cross-sectional surfaces (NW
      D ) of said chokes being smaller than the nozzle cross-sectional surface (NW
      Y ) of the relevant second level control valve (27; 28) (NW
      D Y ).

    • The invention relates to a pressure control device (28) for a tire inflating system (30) of a motor vehicle, said device receiving (134) compressed air via a ventilating inlet (32), activating (142) at least one seal for sealing an air chamber (98) between a stator (90) and a rotor (92) of a rotary feedthrough (14) via a seal actuating outlet (36), and ventilating a tire (12) of the motor vehicle at a ventilating outlet pressure via a ventilating outlet (34) and via the rotary feedthrough (14). The pressure control device (28) has a control valve (38) that can be controlled pneumatically by means of a control pressure, the ventilating outlet (34) being ventilated (156) at the ventilating outlet pressure by means of the control valve only when the control pressure is at least as high as a defined minimum control pressure (158). The pressure control device (28) further has a compressed air duct such that in response to a pressure build-up (136) at the previously ventilated ventilating inlet (32) at least up to the minimum control pressure, the control pressure and the seal actuating pressure are built up (148, 140) for ventilating purposes (156), but the control pressure is built up (148) to said minimum control pressure in a delayed manner with respect to the build-up of the seal actuating pressure to the minimum control pressure. In this manner, an activation (142) of a seal (100, 100') prior to the ventilation (156) of the ventilating outlet (34) is possible without additional actuating channels. The invention further relates to a rotary feedthrough (14), a tire inflating system (30), a motor vehicle, and a tire pressure changing method (128).
