  • the delivery rate is to be controlled on the pump nozzle by means of a handlebar regulation, and the associated regulating sleeve should be able to be fixed in a swivel position provided on the test bench for attachment to the internal combustion engine without additional attachment means.
  • the leadership remains Even with the fastening screws of the pump nozzle removed, the socket is connected to the pump housing carrying the other components of the pump nozzle by the holding means. If the regulating sleeve has to be removed or inspected, the entire assembly can be removed after removing the holding means, without additional disassembly and assembly costs being incurred on this assembly.
  • the guide bushing which can be rotated in the limited area, can be preset so that the lateral boundary edges of the annular segment-like recess define the maximum pivoting range of the handlebar arm in at least one pivoting direction. This eliminates the need for additional slings.
  • each pump nozzle can be attached to the internal combustion engine housing with a handlebar arm resting on one boundary edge and connected to the regulating linkage in such a way that no further operations for equalizing or adjusting the fuel delivery quantity can be made Internal combustion engine are more necessary.
  • the drive assembly consisting of guide bush, drive plunger and plunger spring remains connected to the pump housing carrying the other components of the pump nozzle even with removed fastening screws of the pump nozzle as well as with removed drive parts or with the pump nozzle removed.
  • the clamping claw fastening of the pump nozzle according to the invention designed according to claims 4 or 5 simultaneously secures the retaining screws of the guide bush and holds the pump nozzle in its installed position on the internal combustion engine housing, wherein according to the characterizing features of claim 5 no additional means for fixing the pump housing in the rotational position are necessary.
  • the holding means can be designed to be relatively weak, since it only has to prevent the components from falling apart, because the forces occurring during operation are caused by the flange of the guide bush and the mounting flange of the pump housing with the internal combustion engine housing fasteners such. B. clamping screws or claws applied or added.
  • FIGS. J, 2 and 3 show the first exemplary embodiment, FIG. 1 as a longitudinal section along the line II in FIG. 2, FIG. 2 as a top view cut in the region of the handlebar arm and FIG. 3 as a partially cut side view of FIG FIG. 4 shows a partial longitudinal section along the line IV-IV in FIG. 5, and FIG. 5 shows a top view partially cut at the line V in FIG. 4.
