Abstract

The hydraulic coupling compensator, for steam coal mining incorporates a radial cylinder or cylinders (3), each with a piston (4) which drives a lever crank arm (5) out of a slotted unit (6, 7, 8, 9) into engagement with a projection (10) on an outer cylinder (2), to create a coupling with the inner cylinder (1). The piston chamber is supplied with oil pressure through non-return valves (14, 15) on separate lines (11, 12) with flow in opposite directions, so that the coupling is broken if pressure in the reverse direction becomes excessive.
