FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering, namely, to systems for creating vacuum in the intake system of an engine. System for creating vacuum contains a baffle valve having a Venturi duct located inside the baffler. Venturi duct is designed to receive inlet air directly from the inlet branch when the Venturi duct is parallel to the direction of the inlet air flow. In this case, the Venturi duct is a first annular Venturi duct located inside with respect to a second annular Venturi duct. First annular Venturi duct is located at the geometric center of the baffler body, and the second annular Venturi duct is located between the edge of the baffler body and the first annular Venturi duct. Also options for systems to create vacuum are disclosed.
EFFECT: technical result is to provide the creation of vacuum for the operation of a vacuum device.
