The device for controlling the displacement for a moving member such as a flap (46) includes a fluid distributor valve (10) actuated by control means (18) and suitable for connecting a single-action actuator (38) to a source of fluid under pressure, or to an exhaust, or for isolating said actuator from said source and said exhaust. The piston rod (40) of the actuator is connected to a moving element (14) of the distributor valve and also to the moving member (46) by common motion transmission means. The invention is applicable, in particular, to controlling flaps in installations for heating and ventilating or for air conditioning motor vehicles. |
