FIELD: rocket engine engineering. SUBSTANCE: system comprises Venturi tubes, sensors provided with flexible comparing members connected with Venturi tubes and overlapped by nozzles, adjusting jets, and flow rate throttle mounted in the main line of one of the components and provided with a piston hydraulic servo motor. The sensors are separated into two working spaces by the comparing member. One of the spaces is free and connected with the throat of the Venturi tube. The other space is provided with a nozzle. The space in the sensor for the Venturi tube in the throttled main line is in communication with the inlet of this tube through a jet. The outlet of the nozzle in this space is in communication with the same space of the other sensor through a jet. The outlet of the nozzle of this sensor is in communication with the low-pressure main line. The servo motor is provided with a hydraulic actuator whose working spaces is in communication with the outlet of the Venturi tube in the throttle main line and with the outlet of the nozzle of the sensor of the other tube. EFFECT: improved accuracy. |
