FIELD: mining, particularly pilot control systems for powered supports and other mining machines used in underground mining.
SUBSTANCE: hydraulic distribution device comprises body and valve shell inserted in body boring. Valve shell comprises slide. Installed on the slide are bush, spring-loaded protective cup, thrust bush and fixing ring. Valve shell is retained in body groove by means of sleeve provided with outer thread.
EFFECT: elimination of discharge pipeline influence on hydrodistributor valve operation, increased nominal inside diameter and, as a result, increased technological cycle operation rate and extended functional capabilities.
