FIELD: treatment plants.

SUBSTANCE: group of inventions relates to separator for separation of contaminants in the form of solid particles, aerosol and fluid from fluid flow, as well as to a system of crankcase ventilation of internal combustion engine containing such separator. Separator for separation of contaminants from fluid flow comprises first input designed for inlet of the first fluid medium flow, containing carried by them contaminants, first and second controlled inertial separators, which are connected to each other in series, and a pump, connected to the second controlled inertial separator and designed to create low pressure zone for suction of the first fluid medium flow through the first and second controlled inertial separators. First controlled inertial separator is connected to the first input of the first inlet of fluid medium flow with the first input. Each of the controlled inertial separators is intended for separation of contaminants from the first fluid medium flow. First chamber designed for inlet of the first fluid medium flow, the second chamber connected with the first chamber at least one opening, made so that the first fluid flow is accelerated when passing through the hole and facing surface of baffle so that contaminants are separated from the first fluid medium flow, and drive to adjust the cross-section of at least one hole in accordance with the pressure difference between fluid pressure in the first chamber and the reference fluid in the third chamber. Crankcase ventilation system has a channel for case gases to feed crankcase gases from the case, and separator, in which the first input is connected with channel for case gases. Internal combustion engine comprises crankcase ventilation system, where pump includes the fourth chamber having the second input of the second inlet of fluid in the fourth chamber, note here that in the second inlet nozzle is located in the form of a convergent nozzle for acceleration of the second fluid medium flow, and the third input of the first inlet of fluid medium flow, the third input is located relative to the second inlet so that the second fluid flow can engage and accelerate the first flow of fluid medium, and where the second input is designed for gas flow under pressure from the turbocharger, and the separator is intended for separation of carter oil of crankcase gases.

EFFECT: high efficiency of crankcase ventilation of internal combustion engine as well as prevention of increase of pressure at the inlet of fluid medium to unacceptable values.
