ABSTRACT:
A servo valve comprising a source pressure valve whose inlet port receives a source pressure and whose outlet port communicates with the output of the servo valve, a pressure relief valve, which may operate independently from the source pressure valve, whose inlet port communicates with the outlet port of the source pressure valve and whose outlet port communicates with a pressure sink, for instance the atmosphere, and an electric circuit which controls both the source pressure valve and the pressure relief valve in such a manner that their actions are cooperative in a certain way. Since the source pressure valve and the pressure relief valves are not linked to each other by any mechanical means, the servo valve is very simple in its mechanical structure, fast in response, and does not require subtle mechanical adjustment.
