ンプの安全回路。 A pump connected to and driven by the rotating body of the brushless motor is built into the housing to which the motor coil of the brushless motor is attached, and the fuel sucked by the operation of the pump is discharged to the outside through the inside of the housing. In the type fuel supply pump, a power supply voltage supplied to the motor coil becomes equal to or higher than a preset specified power supply voltage at a base terminal of a driving transistor that controls on/off of the motor coil to drive the brushless motor. 1. A safety circuit for an electric fuel supply pump, characterized in that a switching element is connected to the base terminal of the driving transistor when it is turned on to connect the base terminal of the driving transistor to ground.
