FIELD: ventilation.
SUBSTANCE: invention relates to ventilation and air conditioning of vehicles. Injection unit comprises a housing having a wall in the form of a "volute", an electric motor comprising a discharge shaft extending in the housing, blade wheel located in the housing and installed on the output shaft to create an air flow along the air flow path in the housing, air flow outlet and the coil cutout. Coil dissector is a membrane located between the wall in the form of a "volute" and air flow outlet, and forms a substantially continuous surface with a wall in the form of a "volute" and with release of air flow along the air flow path. In the first position, the membrane is substantially stretched, and in the second position, the membrane is weakened. Alternatively, the membrane is inflated by the valve in fluid communication with the membrane.
EFFECT: reduced noise and vibration.
