PURPOSE:To easily adjust the maximum value and the minimum value of gas flux by providing an addition circuit for adding an output voltage of a voltage source to a divider output voltage obtained by dividing a control input voltage by a divider, and a circuit for converting an addition circuit output voltage to a driving current of a solenoid proportion valve. CONSTITUTION:Supposing that a valve outlet voltage corresponding to the maximum quantity of combustion Qmax is P2max and a valve outlet pressure P2 corresponding to the minimum quantity of combustion Qmin is P2min, a voltage source output voltage is VB=2.IOR. When a control input voltage Vi is the maximum value Vimax, in order to obtain P2max, a divider 1A output is adjusted in such a manner as to satisfy the equation : aVi=2I1R-VB. Thus, the divider 1A output voltage aVi is adjusted so as to adjust variations in a valve. |
