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.
Claims9
A control module for fluid control in injection systems for injecting fuel at high pressure, having a valve body with one injector piston, in which valve needles of control valves are received, with which valves the pressure buildup or pressure relief of control chambers or nozzle chambers of an injector can be varied, wherein the control valves in the valve body are received parallel to one another and are electromagnetically actuatable, and magnet coils are received in recesses of the valve body or in recesses of insert elements on the valve body, and wherein the recesses of the valve body or of the insert elements are slitted to improve the switching dynamics.
