FIELD: internal combustion engines.
SUBSTANCE: invention relates to engine intake systems. Essence of the invention consists in the fact, that the system, by which the claimed method is implemented, comprises a multiple tap aspirator with a throat tap and a diffuser tap. Suction passages coupled to the throat and diffuser taps, respectively, may fluidly communicate via a leak passage with a flow restriction. During conditions where the pressure at a suction flow source of the diffuser tap is less than the pressure at the diffuser tap, backflow from the diffuser tap may travel through the leak passage into the throat tap.
EFFECT: technical result is higher efficiency of vacuum power actuators.
