The hydraulic throttle (HT) is intended to regulate flowrate of a liquid and is driven by an electrical actuator. It is used as an executive member of the system regulating fuel flowrate in channels of the LRE combustion chamber and gas generator.
The HT provides regulation of a working medium's flowrate within a wide range of flowrates and pressures. Owing to an effective design system with a movable sleeve the HT is distinguished by small required torque and stable hydraulic characteristic within a wide range of pressure drops.
