Apparatus for controlling a plurality of moving members, e.g. the flaps in an installation for heating and ventilating or for air conditioning a motor vehicle, comprises single-acting actuators (46, 48) whose piston rods (50, 52) are connected to rotate the flaps about their respective axes (12, 14), with the actuators (46, 48) being fed from a pressurized fluid distributor (32) which includes moving elements which are respectively connected to control means and to each of the piston rods (50, 52), together with fluid flow servo control means for putting the displacement of one flap under the control of the displacement of another flap.
