In order that this invention may more readily be understood , reference will now be made by way of example to the accompanying drawing , in which the only Figure is an elevational sectional view of a control system in accordance with the present invention.
Referring now to the drawing , the illustrated system comprises a valve 10 which includes a valve body 12 having an inlet 14 into which fluid under pressure is delivercd from a sump 16 by means of a pump 18.The valve body 12 further includes end plates 19 and 21 and inlet/outlet ports 20 and 22.The valve 10 is shown in association with a hydraulic cylinder 24 which has a piston 26 dviding the interior thereof into a chamber 28 and a chamber30.Affoxed to the piston 26 is a rod32 pivotally connected at 34 to a boom 36 which may form a part of a back hoc or like agricultural implement.Couterclockwise movement of the boom 36 may be afforded by introducing fluid under pressure to the chamber 30 through a conduit 38 and exhausting fluid from chamber28 by a conduit 40.In like fashion,clockwise movement of the boom 36 may be afforded by introducing fluid under pressure to the chamber 28 through the conduit 40 and exhausting fluid from chamber 30 through a conduit 38.
