Abstract
An electromagnetic pump in which the ignition sound at the time of starting of a combustor is lowered by delaying a raising speed for the delivery pressure of fuel oil. The delivery pressure of fuel oil is automatically controlled by means of an electronic delay circuit including a silicon controlled rectifier which is phase controlled in synchronism with a power source, a trigger diode, and resistors and condensers used for setting the amount of time delay.
