PURPOSE:To obtain the optimum combustion constantly in a captioned pump used for an oil combustion control device of kerosene or the like with a pump and a motor in one body by keeping the discharge amount of kerosene to be non-linear to the number of revolutions of the motor. CONSTITUTION:A main shaft gear 110 is fixed on the free end of a shaft 11B of a motor M, and engaged with a speed-change gear 120. The speed-change gear 120 is fixed on a rotational shaft of a vane pump 60, and the rotatary power of the motor M is transmitted to the vane pump 6 via these gears 110 and 120. In a governer mechanism 100, weights 101 are fixed on springs 104, and one shaft 102 is constructed into a fixed shaft, while another shaft 103 into a movable one. A discharge regulation valve 70 is controlled in relation to the shift of this movable shaft 103. For the movable shaft 103, a shift amount almost proportional to the square of the number of revolutions of the motor M can be obtained on the basis of the selection of weights 101 and springs 104. Consequently, the movable shaft 103 is connected with the regulation valve 70 for changing the discharge amount of kerosene almost in proportion to the square of the number of revolutions of the motor. |
