Lift axle valve for controlling vehicle lift axle function has two magnetic valves for filling and emptying bearer bellows for lifting axle in series between drive and lifting bearer bellows

摘要

The valve has first and second magnetic valves (21,22) for filling and emptying the bearer bellows (2,2') for the lifting axle connected in series between the drive axle bearer bellows (1,1') and lifting axle bearer bellows. At least one pneumatically operated valve (31) fills and empties the lifting axle raising bellows and has a pneumatic control connection acted upon by a pneumatic pilot control (8) of at least one of the magnetic valves so that it fills or empties the raising bellows.
