Abstract (en)

[origin: EP0090796A1] 1. Device for adjusting the start of fuel injection of a fuel injection pump for fuel-injection internal-combustion engines, in which a shaft of the fuel injection pump is coupled with the drive shaft in a stationary casing (25) via a bushing (9), which is axially shiftable by a regulating element, with internal toothings (10, 11), which mesh with external toothings (12, 13) of the two coaxial shafts, of which toothings meshing in pairs (10, 12; 11, 13) at least one is inclined relative to the axis, wherein the bushing (9) is rotatingly supported and secured against axial shifting by a holding element, and in which the regulating element engages with the holding element and is actuated electrically depending on operating parameters and is built as an electric motor, characterized in that the holding element is formed by a clutch gear in coaxial arrangement with the bushing, that the clutch gear (18) has an external gear (21) and is screwable in an internal gear of the stationary casing (25) and the regulating element engages with the clutch gear (18) for its rotation and that in the power transmission path from the electric motor (29) to the clutch gear (18) a spring accumulator (41) with initial tension in both directions of rotation is provided.
