ABSTRACT:
A timer mechanism for controlling the scheduling of the flow of fuel through a metering valve to a turbine engine in response to rotation of a scheduling cam by the movement of a power lever from a cut-off position. A temperature compensating apparatus connected to the turbine engine modifies the output of the scheduling cam to compensate for the temperature of the air supplied to the turbine engine and a pressure responsive apparatus connected to the timer mechanism further modifies the output of the scheduling cam to compensate for the atmospheric pressure of the surrounding environment to provide the optimum fuel flow for starting the turbine engine under varied operational conditions.
