Definitions

  • the invention relates to a mechanical speed controller for a fuel injection pump of air-compressing self-igniting internal combustion engines according to the features specified in the preamble of claim 1.
  • a swivel plate with a full load stop can be transferred from a position corresponding to the start position to a position corresponding to the full load position in order to limit the adjustment path of the quantity control element.
  • the adjustment device has the task of shifting the quantity control element at high speeds in the direction of shortage (see the publication "Bosch Technical Instruction, Speed Regulator for Series Injection Pumps", 1st Edition Sept. 30, 1975, pages 38 and 19).
  • a speed controller version of this type allows the delivery characteristic of the injection pump to be adapted to the fuel demand characteristic of the internal combustion engine in the upper speed range.
  • the invention has for its object to realize a negative adjustment in the speed range below the positive adjustment in addition to the positive adjustment by low-cost measures in the generic speed controller, so that an improved adaptation of the delivery rate in the entire load range to the fuel requirements of the internal combustion engine is made possible, especially with the goal of more favorable smoking behavior.
  • a speed controller for internal combustion engines in which the joint fork of the quantity control member has a counterstop for the full load stop of the tab, which is part of an adjustment device, but it is a constructional design with a spring-loaded slider that in their positive Adjustment effect corresponds to that in the flyweights of the flyweight device described above.
  • a speed controller is known from DE 26 56 261 C2, in which a full-load stop slides along a stop track carried by the counter-stop for the negative adjustment, but in which the counter-stop is firmly screwed to the controller housing.
  • a full-load quantity setting device 4 is fastened to the front housing part 3 of the speed controller 1, to the setting slide 5 of which a link 6 projecting into the speed controller 1 is articulated with a full-load stop 7.
  • the tab 6 is operatively connected to a counter stop 8, which is designed as an adjustable bolt, which is fastened longitudinally displaceably transversely to the direction of movement thereof in an articulated fork 12 connecting a control lever 10 with a quantity control member 11.
  • the bolt section 8a protruding from the joint fork 12 is conical, the cone part with the larger diameter facing the tab 6.
  • the bolt section 8a essentially represents a stop track on which the full-load stop 7 (FIG. 2) lying at right angles to the sectional plane of the speed controller 1 (FIG. 2) slides along in the lower speed range in the sense of a negative adjustment.
  • the adjustment is triggered by the flyweight device 13 of the speed controller 1, which swivels the plate 6 as a function of the speed via a spring-loaded rocker arm 14.
  • the flyweight device 13 is already equipped with an adjustment device in the flyweights (not shown), through which a positive adjustment takes place in the upper speed range between n3 and n4.
  • the adjustment path of the negative adjustment - as can be seen from Fig. 3 - extends from n1 to n2, which means that the tab 6 abuts the lower end of the conical bolt section 8a; the position corresponds to the start of adjustment at n 1. With increasing speed, the tab 6 is pivoted counterclockwise until the upper end of the conical bolt section 8a is reached, which corresponds to the matching end at n2 and at the same time an increase in the delivery rate.
  • the stop track does not have to be flat, but can, depending on the delivery rate of the internal combustion engine, run accordingly, e.g. B. arcuate.
  • the tab 6 assumes the position marked with broken lines when the internal combustion engine is at a standstill, so that when starting, the quantity control element 11 designed as a control rod can assume a starting position that goes beyond the full-load quantity position. After the start, the full load quantity is limited by the interaction of the full load stop 7 and counter stop 8.
