Abstract
A pressure control valve for a fuel injection system, in particular a common-rail injection system, for controlling pressure in a high-pressure fuel reservoir, includes a magnetic actuator configured to actuate a spherical valve closing element. The magnetic actuator interacts with a reciprocatingly displaceable armature that is connected to an armature pin in order to transmit a force of the magnetic actuator to the spherical valve closing element. At least one of the spherical valve closing element and the armature pin is axially displaceably guided in a valve piece which forms a valve seat configured to interact with the spherical valve closing element.
