Abstract
A cylinder head cover of an internal combustion engine with a solenoid-controlled injection device using pump-nozzle units designed so that the solenoid valves are supplied with power in a manner that is advantageous from the manufacturing point of view and provides reliable operation. For this purpose, the cylinder head cover covers the entire injection device and contact elements designed as inserts are injected into the cylinder head cover made of plastic in an injection molding process. The contact elements automatically come into a close-fitting contact with contact surfaces mounted on the outside of the solenoid valves when the cylinder head cover is mounted on a cylinder head. The contact elements are combined with contact segments in a central connector mounted on the outside of the cylinder head cover, wherein the power is supplied for the solenoid valves centrally from a controller.
