The return spring (16) for the actuating rod (14) of the servomotor bears against a tubular stop member (18) which is slidably mounted on the rod (14) and which comes to bear, in the rest position of the servomotor, against a reference stop (22), a ring (21) being firmly fixed to the rod (14) when contacting, in an inactive condition of the servomotor, against the tubular stop member (18) after having exerted a pull on the rod (14) bringing the valve seat (12) formed by the valve plunger (13) into full contact with the valve member (10) of the distribution valve means (6) of the servomotor.
