Abstract

1,163,124. Fluid-pressure servomotor systems. L. REXROTH. Sept. 13, 1966 [Oct. 30, 1965], No.40767/66. Heading G3P. A pilot-operated pressure relief valve includes three pilot valves which are set to allow the main valve to open at different pressures. As shown the main valve 8 is seated by spring 7 and inlet pressure acting behind the valve via restricted passage 9 and chamber 10. When the pressure unseats pilot valve 13, the main vlave is opened to connect pump 3 to reservoir 5. When a solenoid operated valve 17 is shifted to the left, chamber 10 is connected to passage 21 containing a second pilot valve 26 set to open at a lower pressure than valve 13. When valve 17 is shifted to the right, chamber 10 is connected to passage 22 containing a third pilot valve 29 set to open at a pressure different to that of valves 13, 26. The various valves can be in a common housing or in a bank of housings.
