FIELD: hydroelectric servo systems that can be used as off-line actuating mechanisms for flying vehicle control systems.
SUBSTANCE: proposed operating mechanism has hydraulic compensator whose spring unit incorporating precompressed spring is changed over when being reset by applying pressure under butt-end of reset plunger which makes it possible to maintain desired level of minimal pressure in operation mechanism irrespective of pressure value. Use is made in operating mechanism of special controller starting algorithm enabling hydraulic cylinder rod stopping valve to lock operating mechanism output section for certain time and to maintain desired level of minimal pressure within operating mechanism when the latter is in service.
EFFECT: improved conditions for keeping disconnected operating mechanism in hydraulic system without maintaining gage pressure.
