Abstract:
PCT No. PCT/DE95/01289 Sec. 371 Date Jun. 12, 1996 Sec. 102(e) Date Jun. 12, 1996 PCT Filed Sep. 20, 1995 PCT Pub. No. WO96/12103 PCT Pub. Date Apr. 25, 1996A fuel injection pump is proposed, with an annular slide (20) that is displaceable on the pump piston by a governor and that has a control edge by which a relief conduit of the pump work chamber can be opened in the course of the pump piston supply stroke; the relief conduit portion emerging from the jacket face of the pump piston is embodied as a radial bore (18), and the fuel stream emerging from it is deflected by a deflection face (34) on the annular slide or a deflection face (76) on the pump piston, in such a manner that the stream is deflected out of the radial plane, avoiding axially active pressure zones, so that varying axial loads resulting from the various diversion events on one another on the control slide are avoided, and thus fluctuations in injection quantity from one injection event to another and the strain on parts of the governor are reduced as well.
