1. An engine control valve comprising: a rotary actuator;a valve shutter with an open position and a closed position;a movement conversion device configured to convert a rotational movement of the actuator into a translational movement of the valve shutter, wherein the movement conversion device comprises a constant-pitch helical connection for driving the translational movement of the valve shutter; andat least one follower attached to the valve shutter and configured to collaborate with a camway of constant pitch,wherein: the helical connection comprises the camway,the movement conversion device further comprises a tubular wall in which the camway is formed,the camway comprises an open slot in the tubular wall, the open slot having a first end that limits the translational movement of the valve shutter in one of the open and closed positions, and a second end that limits the translational movement of the valve shutter in the other position, the slot having the shape of a helicoid extending along the tubular wall,the movement conversion device is monolithic,the at least one follower is mounted to rotate on a bar attached to the valve shutter, the bar being arranged in a volume delimited by the tubular wall so as to collaborate with an input wheel which is driven by the rotary actuator and which is designed to rotate the bar, andthe at least one follower that is mounted to rotate on the bar is a wheel. 2. The valve as claimed in claim 1, wherein the camway comprises two tracks arranged facing one another on the tubular wall. 3. The valve as claimed in claim 1, wherein the input wheel is mounted to rotate on the tubular wall. 4. The valve as claimed in claim 3, wherein the input wheel is mounted to rotate on the tubular wall via a rolling bearing. 5. The valve as claimed in claim 1, wherein a position sensor that senses the position of the valve shutter is positioned in a space delimited by the tubular wall. 6. The valve as claimed in claim 5, wherein the position sensor is a linear-displacement transducer. 7. The valve as claimed in claim 1, wherein the rotary actuator comprises an electric motor that behaves in a substantially linear manner. 8. The valve as claimed in claim 7, wherein the electric motor is a DC motor. 9. The valve as claimed in claim 1, wherein the rotary actuator is connected to the movement conversion device by transmission means which behave in a substantially linear manner. 10. The valve as claimed in claim 1, wherein a drive train from the rotary actuator to the valve shutter is made up of elements that behave in a substantially linear manner. 11. An assembly comprising: a valve comprising: a rotary actuator,a valve shutter with an open position and a closed position,a movement conversion device configured to convert a rotational movement of the actuator into a translational movement of the valve shutter, wherein the movement conversion device comprises a constant-pitch helical connection for driving the translational movement of the valve,a bar attached to the valve shutter,at least one follower attached to the valve shutter and designed to collaborate with a camway of constant pitch; andcontrol means which are programmed to a linear model,wherein the helical connection comprises the camway,the movement conversion device further comprises a tubular wall in which the camway is formed,the camway comprises an open slot in the tubular wall, the open slot having a first end that limits the translational movement of the valve shutter in one of the open and closed positions, and a second end that limits the translational movement of the valve shutter in the other position, the slot having the shape of a helicoid extending along the tubular wall,the movement conversion device is monolithic,the at least one follower is mounted to rotate on the bar attached to the valve shutter,the bar being arranged in a volume delimited by the tubular wall so as to collaborate with an input wheel which is driven by the rotary actuator and which is designed to rotate the bar, andthe at least one follower that is mounted to rotate on the bar is a wheel. 12. The valve as claimed in claim 1, the movement conversion device further comprising a helical torsion spring that returns the valve shutter to the closed position, wherein the helical torsion spring behaves in a substantially linear manner, and wherein the helical torsion spring is disposed about the rotary actuator. 13. The valve as claimed in claim 1, and further comprising: an input wheel mounted to rotate on the tubular wall and driven by said rotary actuator to rotate the valve shutter. 14. The valve as claimed in claim 11, and further comprising: an input wheel mounted to rotate on the tubular wall and driven by said rotary actuator to rotate the valve shutter.
