<p>To provide for universal programming of the ducting in hydraulic or gaseous valves, particularly for servo application, a plurality of superimposed elements are secured together; one of the elements forms a distribution unit with fluid connections therein, which, itself, may be composed of a pair of plates, one having valve openings and cylinder spaces formed therein and the other having valve units matching the cylinder spaces; a selectively replaceable programming plate, having ducts formed therein in accordance with a hydraulic connection program is secured to the distribution unit; the programming plate can be connected to one or more control valves, the alignment of the ducts in the control plate with the piston and cylinder openings in the distribution unit and in the control valves, as well as with selected power output valves being readily determinable and changeable, so that a universally applicable hydraulic unit can be constructed utilizing basic distribution unit components in which the programming plate, only, need to be changed to change the fluid circuit.</p> |
