VALVE ARRANGEMENT FOR CONTROLLING THE STROKE OF A TELESCOPING PROP
The telescopically extendable prop (1) has at the periphery of the intermediate prop (3) abutments (30) which cooperate with a valve (15) before the intermediate prop (3) has attained its highest extended position. The valve (15) stops the extending stroke of the intermediate prop (3) and is releasi...

| description | The telescopically extendable prop (1) has at the periphery of the intermediate prop (3) abutments (30) which cooperate with a valve (15) before the intermediate prop (3) has attained its highest extended position. The valve (15) stops the extending stroke of the intermediate prop (3) and is releasing the beginning of the extending stroke of the top prop (4). As soon as a predetermined pressure is built up in the consolidating conduit (10) of the top prop (4), the valve (27) subjected to this pressure is overacting the valve (15) cooperating with the abutments (30) of the intermediate prop (3), whereupon the consolidating stroke is completed by pressurizing the intermediate prop (3) with pressurizing fluid.
