Definitions

  • a pressure control valve in which the pressure control valve is open when the internal combustion engine is at a standstill, which means that a connection from the high-pressure accumulator to a low-pressure line is released by a closing element.
  • the pressure regulating valve has a magnetic actuator that is energized to close the closing element, in which an armature places the closing element in a valve seat.
  • a spring element is provided which acts against the magnetic force of the magnetic actuator and thereby moves the armature and an armature bolt attached to it in the opening direction. This lifts the closing element off the valve seat and releases a hydraulic return connection between the high-pressure accumulator and the low-pressure line.
  • the hydraulic return connection to the low-pressure line takes place from a valve chamber downstream of the valve seat, from which bores branching off radially to the side are provided, which open into a low-pressure line in the housing of the high-pressure accumulator.
  • DE 10 2010 043 097.7 and the U.S. 5,549,274 A also relates to a pressure control valve.
  • This serves to open or close a drain of a high pressure accumulator for an injection device for internal combustion engines and comprises a valve element.
  • This is operated by a solenoid actuator.
  • the solenoid actuator acts by means of an armature on a closing element which closes or releases a hydraulic connection from the high-pressure accumulator to a valve chamber.

  • the anchor plate is movably arranged in an anchor space.
  • the valve chamber is hydraulically connected to a low-pressure connection.
  • the armature chamber is hydraulically connected to the valve chamber via a return connection.
