内燃機関用燃料ポンプ。 A rotary pump and an electric motor for rotationally driving the pump are provided in a cylindrical casing,
In a fuel pump for an internal combustion engine, a brush is brought into pressure contact with a spring on the outer circumferential surface of a commutator that is provided at the end of an armature of the motor and rotates together with the armature. A fuel pump for an internal combustion engine, characterized in that the pump discharge pressure in the casing is applied to a diaphragm so that as the pump discharge pressure increases, the contact pressure of the brushes decreases.
