HYDRAULIC BOOSTER Russian patent published in 2007 - IPC F15B3/00

Abstract RU 2307960 C1

FIELD: servodrives.

SUBSTANCE: proposed hydraulic booster has sleeve, movable bushing and spool with three working belts, intermediate belt and guide. One of control chambers is arranged from side of free end face and is connected with channel made in spool which communicates through smaller diameter throttling hole with second control chamber around intermediate belt, and by larger diameter throttling hole, with surface of guide on which movable bushing is installed to form throttle of first cascade.

EFFECT: increased efficiency, provision of quick response, enlarged frequency range, improved dynamic characteristics-stability and quality of transient process.
