Feed device with delivery pumps and filters for diesel fuel in the case of an internal combustion engine

摘要

In the case of a device for feeding diesel fuel from a storage tank to the injection pump of an internal combustion engine with a main and a predelivery pump (2') for drawing in the fuel, a prefilter (3) and a main filter, a venting valve (4) between predelivery pump and main filter and a pressure maintaining valve between main filter and main delivery pump and a bypass valve arranged in a bypass line to the predelivery pump the feedlines and the said functional parts are structurally combined in one filter head (1) of the main filter. The filter head (1) is formed as a casting or press forging into which the connecting lines and the receiving devices for the functional parts are formed or subsequently machined out of the solid material. <IMAGE>
