Claim Text:
1. A pressure regulating valve for a high-pressure accumulator, comprising: a magnetic actuator having a magnet core with contact pins and a magnet armature with an armature plate, wherein the contact pins projecting out of a magnet core face surface and extending through leadthroughs formed in the armature plate, wherein the armature plate being arranged movably in an armature chamber that is hydraulically connected via a pressure equalization duct to a valve chamber that is connected to low pressure; and a residual air gap disk arranged between the magnet core and armature plate, the residual air gap disk having further leadthroughs that correspond to the leadthroughs for the contact pins, wherein the pressure equalization duct has, on the magnet core face surface, an opening via which the pressure equalization duct issues into the armature chamber, wherein a passage for the fuel is configured, for pressure equalization, from one face side of the armature plate to the opposing face side of the armature plate, the passage being formed by at least one of the leadthroughs in the armature plate, and wherein the further leadthrough in the residual air gap disk that is situated in the vicinity of the opening has a radial extension extending in the direction of the opening.
