HYDRO-SYSTEM OF MINING MACHINE

摘要

A hydro-system of mining machine has a tank connected by suction, discharge lines and pressure mains to the block of unloading of hydro-system from pressure and the block for controlling the non-reverse executive mechanisms. The unloading block of the hydro-system for pressure release and control block of non-reverse executive mechanisms are arranged as one three-position electro-hydro-dispenser. In one of its positions the pressure mains and the discharge line are connected, and in the other position û the pressure mains and the non-reversible executive mechanisms.
