ABSTRACT:
An injection valve includes a housing that movably accommodates a needle. A movable core is axially movable together with the needle in the housing. A stationary core is fixed in the housing for forming a magnetic circuit together with the movable core. At least one of the movable core and the stationary core has an end that has an annular first protrusion protruding toward an end of an other of the movable core and the stationary core. At least one of the movable core and the stationary core has an end that has an annular second protrusion protruding toward an end of an other of the movable core and the stationary core. The first protrusion is substantially coaxial with respect to the second protrusion.
