Abstract
The invention relates to a suction pulser (1) intended for a heating, ventilation and/or air-conditioning device of a motor vehicle, including a turbine (2), separation means (14) capable of defining a first air-flow channel enabling the flow of a first air stream intended to pass through a first axial portion (5) of the turbine (2) and a second air-flow channel enabling the flow of a second air stream intended to pass through a second axial portion (6) of the turbine (2). The separation means comprise a tubular member (14) defining an inner space forming at least one portion of the first air-flow channel, the second air-flow channel extending outside of the tubular member (14). A filter (35) is mounted upstream from the turbine and the tubular member in a housing (21).
