A high-pressure connection device with a housing having a receiving opening into which an inlet conduit discharges. A pressure tube connector stub discharges on one end into an end face of the connector stub and has a male thread, which engages a female thread in the receiving opening press a sealing face on the connector stub into the receiving opening into contact with a seat face of the receiving opening. Both threads are embodied as sawtooth threads, and the thread flanks, which are embodied at least approximately perpendicular to the longitudinal axis of the female thread, rest on one another with nonpositive engagement in the tensed state.

High-pressure connection device

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.
