Abstract
An electromagnetically-actuated fuel piston pump is constructed so as to eliminate the distracting pumping noises occurring during the functioning by using a dampening elastic element arranged at a site protected against contact with the delivered fuel by seals. The seals accomplish a bearing of the cylinder, which simplifies the fabrication.
