Device for Monitoring the sicronismo between a Cylinder and a Cylinder backward Push caps in a Frame of estibiamiento exploration for underground mines

摘要

Element for Monitoring the Synchronism between a Cylinder and a Back Thrust. It consists of a series of multi Way Valves and Pipes for Union. The Hydraulic Jack is high and can not always carry out in Mining, underground.The Invention features the valve Activated by the Control unit and control Pipes connected to the spaces of the Recoil Cylinder piston and push. The Plunger is then separated from the driving pressure p as the reflux T driving.
