FIELD: hydraulics. SUBSTANCE: invention can be used in aircraft control system. Proposed actuator contains duplicated spool-type cylindrical distributor. Main spool is installed with axial alignment inside duplicating spool. Duplicating spool is provided with pair of eccentric grooves in which edge of main spool is fitted. One of spaces formed by grooves is constantly connected with drain, and the other, with channel of electrohydraulic valve. Constant-value pressure is supplied to both sides of said space it gets into space when duplicating spool moves. Main spool automatic wedging is built into channel of electrohydraulic valve. EFFECT: prevention of spontaneous release of main spool. 1 dwg
