Document Type and Number:
Japanese Patent JPH11503804
Kind Code:
A
Abstract:
A mechanical governor for use in a fuel management system having a fuel metering loop responsive to an electronic computer for supplying fuel to a combustion chamber of a turbine. The mechanical governor includes a cylindrical spinning spool valve assembly located in a bore which is responsive to an operational force derived from the rotation of the turbine. In a first mode of operation, communication of control pressure Pc to an integrator valve assembly is inhibited by a first spring associated with the spool valve assembly while in a second mode of operation communication of an operational fluid pressure Px derived from the control pressure Pc is communicated to the integrator valve assembly after an operational force corresponding to the rotation overcomes the first spring. In the first and second modes of operation, fuel is supplied to the combustion chamber as a function of a pressure differential across the fuel metering loop. Movement of the spool valve assembly is opposed and fuel is supplied to the combustion chamber under the first and second modes of operation until an operational force overcomes a second spring and the pressure differential across the fuel metering loop is lowered to reduce the fuel supplied to the combustion chamber and correspondingly the rotation of the turbine to prevent an over speed condition.
