Abstract

An hydraulic distributor 8 is controlled from a supply located at a distance. Pressure reduction valves 11, 12 operate as relays between the control 1, 2 and the slide valve of the distributor. In the very long pipes there circulate only pressure impulses of very low output. Input to either valve moves a slide to communicate an output chamber 9 or 10 with a pressure supply 13 until the slide is balanced by equal forces in the input and output chambers. <IMAGE>
