摘要： The invention relates to a level control arrangement for a vehicle having air springs (8) via which the chassis of the vehicle is suspended relative to at least one vehicle axle. A pneumatically-controllable directional-control valve (18) is arranged between the compressor (4) and the air dryer (6) and the directional-control valve (18) has two control inputs (20 and 22). In the base state of the level control arrangement, the compressor (4) is connected via the pneumatically-controllable directional-control valve (18) to the air dryer (6). When the control line (26) of the first control input (20) is connected via a controllable directional-control valve (30) to the atmosphere, the pneumatically-controllable directional-control valve 18 transfers into the other switching state and the air spring (8) can be vented via the air dryer (6). The pneumatically-controllable directional-control valve (18) permits large flow cross sections to be switched so that the air dryer (6) can be rapidly vented when venting the air spring (8) and a regeneration of the air dryer (6) is then possible in an especially advantageous manner.

摘要： The invention relates to a level control arrangement for vehicles having air springs (6a) to (6d) and a pneumatically controllable directional valve (26). A residual pressure holding function and an overpressure function are integrated into the directional valve (26). The directional valve (26) is controlled by the air pressure in the air springs (6a) to (6d). The air pressure can be applied via a control line (20) to a control input (24) of the directional valve (26). The air from the air springs (6a) to (6d) is released with the aid of the venting line (28). The venting line (28) is guided separately from the control line (20) through the directional valve (26). In this way, a large air flow can be conducted through the venting line (28) without the static air pressure in the control space (50) of the directional valve (26) being reduced. The venting line is blocked by a stepped piston (44) of the directional valve when no air is to be released from the air springs.

摘要： A pneumatic suspension and damping arrangement (100) is fixedly mounted on the chassis at the upper region and to the wheel mount at the lower region thereof. The arrangement includes two hermetically closed air springs (101, 102) filled with pressurized gas, whose volumes can be changed and which are connected via an air connection (134) to a pressurized gas source. The air springs are each enclosed by a movable wall formed by a flexible member (116, 124) and each roll off on a roll-off contour and are connected to each other via a throttle element (108) through which the gas can flow in two directions. The air springs are arranged one above the other and the roll-off contour of the first air spring (101) is defined in such a way by the second air spring (102) that the first air spring (101) rolls off on the second air spring (102). A connecting element of the upper cover (104) ) with the roll-off piston (128) of the second air spring (102) runs outside of the two air springs (101, 102).

摘要： A motor vehicle air spring has an air volume subdivided into an air spring volume and an ancillary volume. The two volumes (4, 6) are connected to each other by a line (8) having a cross section which can be switched or continuously adjusted by a valve (12). The valve (12) has two roll membranes (56, 58) which are arranged in mutual opposition. The intermediate space (60) between the roll membranes (56, 58) preferably communicates with the atmosphere. The two mutually opposingly mounted roll membranes (56, 58) can be joined to form a single double roll membrane (76). Preferably, the valve body (34) as well as the bore (62) of the valve housing (36) is configured so as to be cylindrical so that the constant effective diameter (Dw) of the roll membranes (56, 58) results which is independent of the deflection of the valve body (34). The valve (12) is applicable to all areas where a large cross section has to be completely cleared with small switching times and forces and where only little switching energy is available.

摘要： A valve (12) for a motor vehicle air spring (2) having an ancillary volume (6) provides a finely metered continuous opening up to the complete cross section without throttle and a stable performance for flow forces results. The valve (12) is characterized by a star nozzle (50) which includes any desired number of slots nS (52) which mutually intersect and each slot has the length DS (58) and a width sS (56) and the slots are arranged so as to be concentric. The star nozzle peripheral length LUS (64) is increased compared to a round nozzle LUR. For the valve cross section, AVS=LUS·HS applies. The throughput cross section ADS of the star nozzle (50) is so large that it corresponds at least to the cross section AL of the inlet (68) and the outlet (70). A preferably triangular-shaped valley-like recess (66) is provided between each two mutually adjacent ones of the slots (52). The sealing body (40) of the valve (12) is preferably configured as a collar. The valve (12) can be provided with a second collar (74). The star nozzle valve (12) is applicable in all areas where a large cross section must be completely cleared at low switching times and forces.
