Abstract

The invention relates to a pressure control valve for a high pressure accumulator (22) of an injection device of an internal combustion engine comprising a magnetic actuator (10). The magnetic actuator (10) has a magnetic core (30) having contacting pins (41a , 41b) and a magnetic armature (33) having an armature plate (34) , wherein the contacting pins (41a , 41b) protrude from a magnetic core end face (31) and pass through feedthrough (43a , 43b) formed in the armature plate (34). The armature plate (34) is movably arranged in an armature space (44) , which is hydraulically connected by means of a pressure equalization channel (50) to a valve chamber (23) connected to low pressure. The pressure equalization channel (50) has an opening (51) on the magnetic core end face (31) , by means of which opening the pressure equalization channel (60) opens into the armature space (44). Furthermore , a passage for the fuel from one end face of the armature plate (34) to the other end face of the armature plate (34) is provided for the pressure equalization , which passage is formed by at least one of the feed through(43a, 43b) in the armature plate (34). A residual air gap disk (50) , which has further feed through(53a , 53b) in correspondence with the feed through (43a , 43b) , is arranged between the magnetic core (30) and the armature plate (43). The additional feed through (53b) in the residual air gap disk (50) lying near the opening (61) has a radial extension (54) that extends in the direction of the opening (61).
