Abstract

The invention relates to a control module for fluid control in injection systems, having a valve body (2) in which valve needles (6, 24) of control valves (5, 17) are received. With these control valves (5, 17), the pressure buildup or pressure relief of control chambers (30) or nozzle chambers of injectors can be varied. The control valves (5, 17) in the valve body (2) are electromagnetically actuatable, and magnet coils are received in recesses (9, 20) of insert elements (19, 32) or in recesses (9) in the valve body itself.
