Abstract

A high-pressure fuel system for internal combustion engines, having a housing that contains two high-pressure bodies. The high-pressure bodies rest with contact surfaces at least indirectly against each other and are pressed against each other by means of a tensioning device. A supply conduit is embodied in the high-pressure bodies, which carries highly pressurized fuel and passes through the contact surfaces of the two high-pressure bodies. A sealing film is disposed between the two high-pressure bodies, which encompasses the passage of the high-pressure conduit and thus assures a favorable seal.
