Abstract

The invention relates to a pressure regulating valve for regulating pressure in a high pressure fuel accumulator for an internal combustion engine comprising a valve piston (5) accommodated axially displaceably in a bore (1) in a valve housing (2) acting on a valve closing member (3) in the direction of a valve seat (4) said valve piston being connected at the end thereof facing away from the valve seat (4) to an armature (6) of a magnetic assembly (7) for actuating the pressure regulating valve wherein the armature (6) is accommodated in an armature chamber (8) and the valve closing member (3) is accommodated in a valve chamber (9). According to the invention the valve chamber (9) and the armature chamber (8) are hydraulically connected via at least one groove (10) and/or bore (11) formed in the valve housing (2) valve piston (5) and/or in the armature (6) as well as at least one choke point (12).
