    • The invention relates to a device (100) for regulating the pressure in at least one pair of air bellows (106, 107; 109, 110, 108, 111; 112, 113), which device (100) comprises at least three pairs of bellows (106, 107; 109, 110, 108, 111; 112, 113) each situated between an axle (103, 104, 105) and the frame of a vehicle, two air connections (114, 115) and first and second valve blocks (101, 102) each comprising at least two valves (116, 117, 118; 119, 120, 121), which air connections (114, 115) are arranged to supply compressed air via said respective valve blocks to said pairs of bellows, which at least two valves in said valve blocks are arranged to regulate the pressure level in said pairs of bellows. According to the invention the device comprises a further valve (136, 137, 138) situated between a pair of bellows (106, 107; 109, 110, 108, 111; 112, 113), which further valve (136, 137, 138) in one position is arranged to empty one of a pair of bellows (106, 107; 109, 110, 108, 111; 112, 113).
      The invention relates also to a transport vehicle comprising a device according to the present invention.
    • 本发明涉及一种用于调节至少一对空气波纹管(106,107; 109,110,108,111,112,113)中的压力的​​装置(100),该装置(100)包括至少三对 每个位于车轴(103,104,105)和车辆框架之间的波纹管(106,107; 109,110,108,111,112,113),两个空气连接(114,115)和第一和第二阀 每个包括至少两个阀(116,117,118,119,120,121)的气缸(101,102),其中空气连接(114,115)被布置成经由所述相应阀块将压缩空气供应到所述波纹管对 其中所述阀块中的至少两个阀被布置成调节所述波纹管对中的压力水平。 根据本发明,该装置包括位于一对波纹管(106,107; 109,110,108,111,112,113)之间的另一个阀(136,137,138),其另外的阀(136,137,138) )排列成一对波纹管(106,107; 109,110,108,111,112,113)中的一个。 本发明还涉及包括根据本发明的装置的运输车辆。
