Abstract RU 2493382 C2

FIELD: engines and pumps.

SUBSTANCE: control system 1 comprises throttle 4 arranged in offgas channel 5 and throttle actuator 6 with control link 7. Offgas pressure control device controls offgas pressure P₁ in channel 5 upstream of offgas throttle 4. For this, control link 7 incorporates control actuator 9 interacting with pressure balance volume 10. Note here that said pressure balance volume 10 is communicated with offgas orifice hole 11.

EFFECT: longer life, decreased noise.
