The invention relates to suction device provided with a pipe which is directly or indirectly connected to the cylinder of an internal combustion engine when said device is mounted thereon. The suction device also comprises a shutter blade (5) arranged on an axis (7) and disposed in the pipe in such a way that it generates, in a defined position, a transversal or longitudinal vortex in the cylinder. Said shutter blade comprises at least one slot (11, 16) extending on the side of the shutter blade oriented towards the main flow direction (9) of the pipe until a side which is opposite the main flow direction (9) of the pipe is reached. When the engine operates, the slot (11, 16) is crossed by a gas stream in the main flow direction (9), thereby producing pressure compensation. |
