ABSTRACT:
A device for supplying an internal combustion engine with fuel has a supply container from which the fuel is supplied and having an opening, a feed pump arranged in the supply container and insertable into the supply container through the opening, a closure part for closing the opening of the supply container, a pressure regulator arranged on the closure part and having a pressure chamber with a connection to a pressure side of the feed pump, to an internal combustion engine and to an unloading chamber, the closure part having a flange-shaped base body which closes the opening and is provided with a depression, a pipe formed of one piece with the body for forming a connection of the pressure chamber to the unloading chamber and extending into the depression, an elastically deformable diaphragm group which closes the depression for forming the pressure chamber, the pipe having a seat with which diaphragm group at least partially directly cooperates, a spring loading the diaphragm group toward the pipe so that during the exceeding a predetermined pressure in the pressure chamber the pipe for connecting the pressure chamber with the unloading chamber is released, the diaphragm group being mountable to the base body, a holding element arrangeable on the closure part, and an insert part engageable with the spring and movable axially relative to the holding element.
