METHOD OF CONSTRUCTION OF DRIVE AND DRIVE FOR REALIZATION OF THIS METHOD (VERSIONS) Russian patent published in 2006 - IPC F16K31/12

Abstract RU 2289053 C2

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.
