METHOD OF CONSTRUCTION OF DRIVE AND DRIVE FOR REALIZATION OF THIS METHOD (VERSIONS)

摘要

FIELD: manufacture of fittings; pneumo-hydro-automatics; control of shut-off adjusting fittings. ^ SUBSTANCE: proposed method consists in connection of cavities of drive to pipe line before and after shut-off adjusting fittings through constant and varying hydraulic restrictors. Ratio of areas of flow sections of constant restrictors and capacities of cavities corresponds to preset mathematical dependence. ^ EFFECT: enhanced efficiency. ^ 7 cl, 5 dwg
