Abstract
PURPOSE: To improve a linearity of control pressure over an input current of an electromagnetic coil for the sake of a magnetical pressure control valve used for control of combustion intensity in a combustor provided with a return nozzle.
CONSTITUTION: A needle valve 13, pressed to a valve seat part 9 by an operation point adjusting spring 14, controls a pressure in an inlet 8 by actuating an electromagnetic force of an electromagnetic coil in the direction opposite to that said spring 14. The force of the spring 14 is established at an intensity maintaining the needle valve 13 in a closed condition in a partial field of a low electromagnetic force within a varying range of said electromagnetic force. Thus, said spring 14 controls the pressure in the inlet 8 in a low electromagnetic field representing a nonlinear part, while both the spring 14 and the electromagnetic force control said pressure, starting from the linear part of said electromagnetic field.
