Abstract

The present invention relates to a fuel high-voltage pipeline installation device for fixing a fuel high-voltage pipeline (10) on a fixing section (13) of an IC engine component. The installation device is arranged with a differential nut (17) with an outer screw thread (20) and an inner screw thread (22) which pitches are various and rotary directions are same, a slide nut (18) with outer screw thread (23) and a restraint nut (19) with inner screw thread (26). The restraint nut can be screw down with the fuel high-voltage pipeline (10) until reaching a stop of the restraint nut; the slide nut (18) can be guided into a straight through hole (21) of the differential nut (17) from one side, and can be screw down with the inner screw thread (22) of the differential nut (17) by the outer screw thread (23) until reaching a stop (24) for the slide nut (18), and the restraint nut (19) can be guided into the straight through hole (21) of the differential nut (17) from the second side, so as to fix the restraint nut (19) and the slide nut (18) by means of preventing motion relatively.

Description

technical field [0001] The invention relates to a high-pressure fuel line mounting device for fastening a high-pressure fuel line to a fastening section of an internal combustion engine component and to a method for fastening a high-pressure fuel line to a fastening section of an internal combustion engine component using the mounting device. Background technique [0002] DE 37 39 937 C2 discloses a fuel high-pressure line, which can be used, for example, in a diesel internal combustion engine for feeding fuel under high pressure, for example from a high-pressure fuel pump, to an injection valve of the internal combustion engine. The fuel high-pressure line disclosed here has a high-pressure line in which high-pressure openings are arranged, wherein the high-pressure line is surrounded by a sleeve. The high-pressure fuel line according to DE 37 39 937 C2 correspondingly has a connection at its end, wherein such a connection enables fastening of the high-pressure fuel line to...
