  • Shut off/pressure regulating valve for turbine engine
    Patent number: 4876857
    Abstract: A shut off and pressure regulator valve (10) for use with a metering valve (12) in a fuel system for a turbine engine. A pressure responsive piston (70) freely moves in a sleeve (48) to initiate fluid communication between an inlet port (16) and an outlet port (24). In response to a predetermined pressure differential a seal (90) carried by the piston (70) engages a ramp (56) to prevent fluid communication through the operational clearance (x) between the piston (70) and sleeve (48) to prevent fluid communication of a control fuel from a control chamber (76) to the outlet port (24) connected to the turbine engine.
