METHOD OF DISTRIBUTION OF LIQUID FOR HYDRAULIC CONTROL OF MECHANISMS OF PIT BORING RIG Russian patent published in 2008 - IPC E21B19/08

Abstract RU 2336406 C2

FIELD: mining.

SUBSTANCE: invention refers to the hydraulic actuation mechanism of the pit boring rig, intended for drilling blast boreholes in rocks. The technical result is reached by means of the controlled and safety built-in valves collected in a single unit. Liquid is distributed by three small-sized similar three-dimensional units with electro-hydraulic control, hydraulic impacts and substantial leaks being excluded.

EFFECT: increased performance of the pit boring rig.
