ACTUATOR Russian patent published in 1997 - IPC

FIELD: space engineering and rocketry. SUBSTANCE: the actuator uses a three-gear pump, relay, bell-crank, control valves attached to the bell-crank on a flexible mounting made in the form of a wire link and placed in the hollow axles of the three-gear pump. The end of the wire link opposite the control valve is secured in a rod, which is furnished with an assembly for its displacement relative to the bell-crank. An assembly preventing the relative turning of the control valve and rod relative to the wire link is made between them. The assembly for displacement of the rod relative to the bell-crank is made in the form of a male thread on the rod similar to the threaded hole made in the bell-crank, and a lock-nut. The preventing assembly is made in the form of stops engageable with each other and positioned on the ends of the control valve and rod facing each other. EFFECT: improved design. 3 cl, 1 dwg
