Abstract:
1. A high-pressure pump for a fuel injection device of an internal combustion engine, the pump comprising, at least one pump element, which has a pump piston that defines a pump work chamber and that is driven to a reciprocating motion at least indirectly by a drive shaft counter to force of a restoring spring, a sleevelike tappet bracing the pump piston at least indirectly on the drive shaft the restoring spring engaging at least the pump piston, a support element inserted into the tappet, on which support element the pump piston is braced toward the drive shaft and which support element is braced at least indirectly on the drive shaft, and the restoring spring engaging the pump piston and the tappet via a spring plate; the spring plate being elastically deformable in the direction of motion of the pump piston such that by its elastic deformation, deviations in the position of its contact faces on the pump piston and on the tappet are compensated for.
