A linear pneumohydraulic drive with electrorheological (ER) control is considered to ensure movement speed of objects according to a given law. The high accuracy of movement speed maintaining of is ensured by the use of a starch-based liquid as a working medium, capable of almost instantly changing rheological properties under the action of an electric field. Calculations of potential distribution in the ER valve is carried out, as well as calculation of the flow velocity of the ER fluid in the throttle and pipelines. It has been experimentally established that effective adjustment of drive rod movement speed is carried out at air pressure of 0.4 atm at the inlet to the pneumatic cylinder and a volume concentration of working fluid dispersed phase of 25%.
