Definitions

  • Generic regulating devices are known from DE-PS 564 169 and DE-OS3 406 646. Furthermore, it is known from DE-PS-2 950 633 to move the reciprocating actuator of a fuel injection pump by an axial force, regardless of the position of the lever, into an end position which corresponds to the zero delivery of the pump piston. Locking the reciprocating actuator changes the position of the lever regardless of the current position of the rotatable member. As a result, the driver device is displaced from its rest position against the force of the return spring. The return torque then resulting on the lever acts via the rotatable member on the regulator of the internal combustion engine coupled to the regulating device and undesirably reduces the working capacity of the regulator.
  • the arrangement can be assembled in a simple manner, that the arrangement requires little installation space, that the decoupling between the fog and the rotatable member works without any effect on the connected controller, that the return spring of the lever works without restriction the controller working capacity can be dimensioned and that vibrations of the regulating device and the resulting frictional wear are avoided with a larger spring preload of the return spring.
  • the actuator 14 sets the piston 17 of the fuel injection pump 11 in a known manner to different delivery rates.
  • the lever 13 consists of a housing 15, which has a plain bearing-like transverse bore 29 for receiving the rotatable member 12, a piston-like spring plate 16, which is arranged in a cylinder bore 18 of the housing 15, and a return spring 19 clamped between the housing 15 and the spring plate 16.
  • the spring plate 16 has, on the side facing the rotatable member 12, a prismatic extension 20 which rests with its end face under prestress by the return spring 19 on a secant surface of the rotatable member 12.
  • Spring plate 16 and rotatable member 12 form a torque-limiting driver device in the interacting area.
  • the rotatable member 12 has an axially parallel bore 21, which via a controllable valve 23 with a pressure oil source 24, for. B. the lubricating oil system of an internal combustion engine is connected.
  • a bore 22 branches off radially from the bore 21 and opens within the housing 15 in the bearing gap, which is shown enlarged in FIG. 1, between the transverse bore 29 and the rotatable member 12.
  • the pressure oil penetrates through the bearing gap into the cavity 25 between the spring plate 16 and the rotatable member 12.
  • the spring plate 16 is raised up to the stop 26 by the pressure building up in the cavity.
  • the connection between the prismatic extension 20 of the spring plate 16 and the secant surface of the rotatable member 12 is thereby broken and the torque transmission of the driver device is interrupted.
  • the spring 27 now presses the actuator 14 while driving the lever 13, regardless of the position of the rotatable member 12, in the end position designated 28, which corresponds to the zero delivery of the fuel injection pump 11.
  • the hydraulic notching of the driver device prevents the generation of a reverse torque on the rotatable member 12, so that there is no reduction in the controller working capacity due to the fuel injection pumps being switched off.
