ABSTRACT:
An electromagnetic injection valve in which the spring acting between an iron core and a valve closure member is made of spring steel. The iron core is formed as a round rod which is reduced in diameter at the end thereof forming a stop surface for the valve closure member. A protruding support ring of nonmagnetic material is fixed to the valve closure member for the guidance of the spring, such that the turns of the spring are spaced from the surfaces of the reduced diameter end of the rod and the valve closure member in the region of the air gap between the rod and valve closure member by at least an amount equal to the reduction in diameter of the end of the rod.
