ELECTROHYDRAULIC DISCRETE ROTARY DRIVE Russian patent published in 2018 - IPC F15B9/03 

FIELD: machine building.

SUBSTANCE: electrohydraulic discrete rotary actuator is designed to control the executive bodies of missiles, aircraft and other devices. Drive consists of a power module consisting of a body with cavities made in it and two hydraulic pistons rotating an executive shaft, which is associated with a feedback rod and a telemetric shaft position sensor; a control system comprising a stepper motor, a steering wheel, a planetary gearbox consisting of a central gear, three satellites, outer wheel and a carrier, while the planetary gearbox is connected through a pinion and a control rail with a cylindrical distributing spool to which the channels for draining and pumping the working fluid are supplied, and has a feedback from the output shaft via the feedback rod, the feedback rod being mechanically coupled to the outer wheel of the planetary gear through a transmission consisting of a shaft with two toothed wheels mounted on it.

EFFECT: creation of electrohydraulic discrete rotary actuator with autonomous control system, improving the process design and reducing the cost of production.
