Embodiment Construction

[0023] figure 1 According to a possible configuration, a fuel injection device is shown in a schematic perspective view with a fuel distributor 2 and a plurality of holders 3, 3A, 3B, 3C for connecting the distribution pipe 4 of the fuel distributor 2 It is fastened to a schematically shown additional mounting structure 5 . The holder 3 here includes a threaded rod 6 , by means of which the holder 3 can be screwed onto the additional mounting structure 5 . Correspondingly, the holders 3A, 3B, 3C are provided with further screws 6A, 6B, 6C. The additional mounting structure 5 has suitable threaded holes 7 , 7A, 7B, 7C for this purpose. In this exemplary embodiment, three cups 8 , 9 , 10 are arranged on the distribution pipe 4 , which serve to connect fuel injectors (not shown). These fuel injectors can be partially inserted into the bores 11 , 12 , 13 of the additional mounting structure 5 . In this case the additional mounting structure 5 is the cylinder head 5 of the inte...

Abstract

A holder (3) serves for fastening a distributor tube (4) of a fuel distributor (2) to an add-on structure (5). The holder (3) comprises a first half shell (15) and a second half shell (16). An elastically deformable damping element (20) is injection moulded onto a holding region (17) of the first half shell (15). Furthermore, an elastically deformable damping element (22) is injection moulded onto a holding region (18) of the second half shell (16). For the fastening of the distributor tube (4) to the add-on structure (5), the half shells (15, 16) are joinable to each other in such a manner that the half shells (15, 16) surround the tubular component (4) and hold the tubular component (4) by means of the elastic damping elements (20, 22). The first half shell (15) and the second half shell (16) can be connected to each other here by means of a film hinge (28). A further configuration possibility consists in that the damping element (20, 22) is inserted into the relevant half shell (15, 16).

Description

technical field [0001] The invention relates to a holder for fastening a tubular component, in particular a distribution pipe of a fuel distributor, to an additional mounting structure. The invention relates in particular to the field of fuel injection devices for internal combustion engines. Background technique [0002] A vibration-insulated fuel distribution system for internal combustion engines is known from US 7 591 246 B2. In one possible, known configuration, first and second retaining parts are provided. An annular insulator is placed around the tubular distribution pipe, said insulation being arranged between the receptacles of the holding element in the assembled state, wherein the holding element holds the distribution pipe via the insulation, wherein the distribution pipe and maintain contact between components. The fastening takes place via fastening elements which extend through the holding element and are fastened to the cylinder head. [0003] From US 7,...
