Abstract
A pump nozzle for a diesel engine, in which an injection pump element including a pump piston driven by a cam-shaft via a thrust element and a pump element bushing is combined with an injection nozzle to provide a unit to be associated to one motor cylinder. The pump piston is surrounded by a control sleeve which is non-rotatable relative to the pump element busing. The pump piston can be rotated for adjusting its orientation relative to the control sleeve for the purpose of adjusting the supplied amount of fuel. An adjuster for adjusting the amount is disposed at substantially the same level as of the thrust element. The control sleeve is arranged completely within a pump spring, which partly surrounds the pump element bushing. The pump dement bushing is formed integrally with a blind longitudinal bore which receives the pump piston. The pump spring extends from the level of the adjuster for adjusting the amount of fuel to be injected per injection, to the level of the working chamber of the pump piston. This provides an overlapping arrangement of the separate parts of the pump nozzle, so that the structural dimensions of the pump nozzle may be kept small.
