Injection line connection to compression tube of injection valve

摘要

The connection has the compression tube (5) passing through the cylinder head in a coaxial boring to the injection valve. The tube has a connecting piece sealed by conical seats on its end. The connecting piece is in the form of a connecting head (6) with an integrated boring (9) for fuel input. This head is pressed sideways by a screw (8) against the seal seat of the compression tube (5). The injection line (4) is connected to the head by a ring-nut (11). The compression tube may be sealed by an O-ring on the connecting head end of the tube.
