Definitions
- the invention is based on the preamble of claim 1 CH-A 188 413.
- this known fastening device is one of two studs enforced flange provided on a separate pressure sleeve for fixing the injector acts in the cylinder head.
- the pressure sleeve is opposite the non-rotatably arranged flange relative to this via a dowel pin Flange arranged secured against rotation, so that the injection nozzle is secured against rotation caused exclusively by the frictional preload through the pressure sleeve is. If the flange screw connection is loosened, in addition to an insufficient one Press fit cannot rule out the mobility of the injection nozzle.
- a different type of rotation lock for an angle-oriented, secured injection nozzle comprises the fastening device known from DE-B 2 262 570.
- the anti-rotation device comprises a closed double-edge formed in the flange corresponds with two flattenings in the free end area of the injection nozzle.
- For Mounting the flange on the injection nozzle must be provided in the free end area Devices of the injection nozzle must be dismantled.
- DD-A 113 790 is also a fastening arrangement on a cylinder head known in the bearing points for rocker arm carrying bolts on the Rocker arm bearings are also extended to attach a cover for the cylinder head.
- the invention is based on the object, in particular in the free or end area provided with projecting devices on the fuel connection side Injection nozzle to show a fastening device, which is next to one in the fastening area the injection nozzle further simplified an additional embodiment Hold function for another facility allows.
- flange studs additionally the definition of one of the injection nozzle with clamping element Cover hood of the cylinder head serve, the studs via first nuts with means for noise-isolating fixing of the cover are combined and also second nuts of the separate, preloaded Serve bracket of the flange, the one-sided open edge as a recess Two-sided for corresponding stop surfaces on the injection nozzle as a rotation lock having.
- the invention offers the advantage of a simplified assembly of the injection nozzle and flange and secondly the advantage of a reduced number Fasteners for the cover hood.
- Cylinder head 3 of an internal combustion engine, not shown comprises a flange 4 which means in the cylinder head 3 arranged bolt 5 biased the injector 2 acts.
- the flange 4 has a recess 6, which as one-sided open-edged square 7 is designed that over corresponding stop surfaces 8 on the injection nozzle 2 whose angle-oriented bracket on the cylinder head 3 serves.
- the flange 4 acts on one of the injection nozzle 2 separate cylindrical clamping element 9, the is preferably designed as a pressure sleeve 10.
- This Pressure sleeve 10 acts at the distal end with an im
- the outer circumference of the injector 2 can be arranged separately Clamping shoulder 11 together, preferably as an in an outer peripheral groove 12 of the injector 2 arranged Spring ring 13 is formed.
- first nuts 16 serve to fix the cover 14 on the cylinder head 3 and second nuts 17 of the separate, preloaded mounting of the flange 4 for Fastening the injector 2 in the cylinder head 3.
- a cylinder head cover shows and describes DE-A 2 628 692.
