Fluid Apparatus

The fluid apparatus has toggle action type pilot and slave valves which operate in response to fluid pressure impulses. Valves are coaxially positioned.

Pilot poppet valve 1 -2 is positioned by relay 3 and arm 4. This occurs during the low pressure non-pulse interval to seal one of the respective discharges 5 or
6. Upon application of a pressure pulse at 7, the end chambers 8 and 9 have differential pressures in them to position slave valve 10 and also seal the poppet valve. Duct 11 is thus selectively connected to either the pressure source 12 or to sump 13.

A mechanical knockoff 14 restores the poppet valve.
