Patent ID: 8695572

Claim:
A connecting arrangement for a tubular fuel line ( 5 ) which coming from the exterior extends through a passage ( 4 ) in a cylinder head ( 1 ) to a nozzle holder ( 2 ) of an injection nozzle to feed fuel thereto, wherein at its front end towards the nozzle holder ( 2 ) the fuel line ( 5 ) has a pressure nipple ( 6 ) which on its front side has a sealing surface ( 8 ) and on its rear side a pressure receiving surface, wherein the connecting arrangement includes the following: a cap screw element ( 15 ) which coaxially surrounds the fuel line ( 5 ) and which is screwed in the region of the inlet opening ( 3 ) of the passage ( 4 ) and which projects with an axially directed tube portion ( 17 ) into the passage ( 4 ), a pressure transmission arrangement which is arranged in the interior of the passage ( 4 ) and which coaxially surrounds the fuel line ( 5 ) and on which the tube portion ( 7 ) of the cap screw element ( 15 ) in the tightened condition exerts a force which is directed axially towards the nozzle holder ( 2 ) and which is transmitted thereby to the pressure receiving surface of the pressure nipple ( 6 ) to press the sealing surface ( 8 ) thereof against a counterpart sealing surface ( 10 ) which is provided on the nozzle holder ( 2 ) and which surrounds the mouth opening of a fuel flow passage leading further in the nozzle holder ( 2 ), and a sealing arrangement which seals off a first free space ( 21 ) between the outside wall of the fuel line ( 5 ) and the inside wall of the pressure transmission arrangement and a second free space ( 22 ) between the outside wall of the pressure transmission arrangement and the inside wall of the passage ( 4 ) towards the exterior of the cylinder head ( 1 ), characterized in that the sealing arrangement is positioned completely in the interior of the passage ( 4 ).
