MULTIFUNCTIONAL HYDRAULIC SYSTEM Russian patent published in 2012 - IPC F15B11/20 

FIELD: machine building.

SUBSTANCE: hydraulic system is designed to support operation of guidance drives incorporated with surface-to-air missile systems that feature high moments of unbalance. Said system comprises several hydraulic and mechanical adequately coupled elements to allow: lifting launching units by manually-driven pump in case electrical supply or hydraulic system main pump fails, unloading hydraulic system main pump in case control signal does not exist at its input, holding launching unit at whatever elevation in operation on both main pump and manually-driven pump, and downing said unit under action of unbalance moment.

EFFECT: expanded operating performances, higher reliability.
