FIELD: engine engineering. SUBSTANCE: servo-piston is kinematically coupled with a controller of fuel flow rate in the prechamber through a rod. The without-rod space of the servo-piston is coupled with a constant pressure regulator through throttle assemble and nozzle. The device has a unit for control of speed of the servo- piston which consists of slide distributor, having a passage coupled with a pickup for measuring pressure ration on turbine, and throttle assembly, which is coupled to the without-rod space of the servo-piston and constant pressure regulator. EFFECT: enhanced reliability. 1 dwg
