Fuel Pump

Abstract

A fuel pump includes an electromagnetic intake valve including a coil winding portion formed by winding an electromagnetic coil around a bobbin and a magnetic circuit configuration portion constituting a magnetic circuit when a current flows through the electromagnetic coil. The magnetic circuit configuration portion includes a yoke disposed so as to surround the coil winding portion, and a predetermined part facing, across a gap, the coil winding portion in a radial direction of the electromagnetic intake valve. The dimension of the gap is set such that the coil winding portion and the predetermined part come into contact with each other first when an impact force directed from an outer side to an inner side in the radial direction of the electromagnetic intake valve is applied to the yoke or the coil winding portion.
