1. Electrohydraulic height corrector for vehicles comprising a hydraulic distributor (1) with rotary spool formed of a body (2) which is provided with a fluid intake connection (26) connected to a pump, an exhaust connection (25) connected to a reservoir and a user connection (22a or 22b) connected to suspension cylinders and in which the distribution spool (3) is pivotally mounted, this latter being able to occupy three different active positions, means (6) responsive to the position of the suspended part of the vehicle with respect to the non suspended part, and means (4) controlled by the responsive means for acting on the flow of fluid through the distributor, characterized in that one end of the pivoting spool is fixed to the shaft of an electric micromotor (4) with two rotational directions, and in that said height corrector comprises a first potentiometer (6) whose adjustment member has its position related to the position of the suspended part of the vehicle, a second potentiometer (5) whose adjustment member is fixed to the other end of the spool (3), and means (7) for comparing the signals emitted by the two potentiometers and for emitting a signal which is a function of the difference between the first two signals and is applied to the micromotor (4). |
