Abstract: A pressure fluid operated ride leveler which adjusts the actual level of a vehicle body relative to a vehicle axle to a desired level, includes a pressure fluid source and a pressure fluid sink, pressure fluid chambers which support the vehicle body, and a pressure fluid conduit connecting the pressure fluid chambers to either the pressure fluid source or the pressure fluid sink. First and second controllable valve mechanisms are disposed in the pressure fluid conduit. The second valve mechanism is, e.g., a controllable throttling valve, capable of reducing the diameter of the pressure fluid conduit. Both the first and second valve mechanisms are actuated by a control unit. The control unit actuates the first valve mechanism to connect the chambers to the pressure fluid source or the pressure fluid sink based on the difference between the actual level of the vehicle body and the desired level.
