Method for operating dosing pump, particularly for conveying fuel to vehicle heating device, involves rotating pump piston in clockwise and anticlockwise manner between two end positions defined by stop arrangements

摘要

The method involves rotating a pump piston (12) in clockwise and anticlockwise manner between two end positions defined by stop arrangements. The pump piston is assigned to a prestressing device (28) for producing pretensioning force (F-V), which prestresses the pump piston in direction of an end position. The pump piston is assigned to a drive arrangement for producing drive force (F-A), which moves the pump piston against the pretensioning force in direction for another end position.
