Abstract

755,330. Hydraulic mine props. DEUTSCHE KOHLENBERGBAULEITUNG. Jan. 11, 1954 [Jan. 23, 1953], No. 702/54. Class 20(2). Hydraulic mine props 1, 1<SP>1</SP> connected by capboards 2 and ties 3 and adapted to be advanced by a pusher truck, are controlled by an inlet valve 7 and a separate outlet valve 8 in a valve body 11, which are held closed by the hydraulic pressure in the props. These valves are also held closed by springs. The outlet valve has a pre-opening cone 10. An excess pressure release valve 9 is provided.
