ABSTRACT:
This invention relates to a shutter device for the precision control of a flow, comprising at least one organ for shutting a section for the passage of a flow, the motion of which is proportional to that of an actuator controlling it, wherein said device comprises at least two shutter organs controlled by the actuator by means of a transmission allowing to obtain slightly different proportionality coefficients for the motion of said organs.
