FIELD: redundant hydraulic servo drives used as actuating mechanisms in flying vehicle control systems.
SUBSTANCE: filtering units made in form of modules are built directly in hydraulic drive housing. Bypass of working fluid is performed directly to hydraulic drive in case of contamination of filter element above preset limits. Siphon leakage of working fluid from inner chambers of hydraulic drive and supply hydraulic system into external medium at dismantling of filter elements is excluded. Proper mounting of filter elements in the course of operation of hydraulic drive is ensured.
EFFECT: enhanced reliability; facilitated procedure; maintainability; extended functional capabilities of filter elements.
