Abstract

1422532 Hydraulic reciprocating apparatus ENGLISH CLAYS LOVERING POCHIN & CO Ltd 10 April 1973 [14 April 1972] 17418/72 Headings F1A and F1P [Also in Division El ] Hydraulic apparatus especially for oscillating the water jet of apparatus used to wash minerals from the earth, comprises a double-acting ram 7 for oscillating the nozzle, a slave ram 30 connected to the ram 7 by liquid columns in lines 25, 26, a double-acting master ram 31, a rod 32 joining the master and slave pistons, and control means operable to cause the automatic reciprocation of the master piston. The control means comprises a reversing valve 37 controlled by pilot valves 39, 40 operated by a roller 33 movable with the rod 32. The roller 33 operates the pilot valves via members 40, 41, the latter being longitudinally adjustable to vary the stroke of the master piston. A needle valve 27 in the line 25 is adjustable to control the speed of the ram 7. The centre of the oscillations is shifted by manualoperation of a valve 23 arranged to supply liquid to one liquid column while allowing discharge from the other. The supply of oil for operating the master ram 31 is derived from a pump driven by a Pelton wheel driven by the water supplied to the nozzle. A second double-acting ram may be provided, the ram being operable by its own individual control apparatus or by the apparatus described, via a selector valve (not shown).
