Arrangement for supplying internal combustion engine with fuel from supply container

Abstract

An arrangement for supplying an internal combustion engine with fuel has a supply container with an opening, a feed pump insertable into the supply container through the opening, a closure part closing the opening and provided with a pressure regulator 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 pressure regulator has a spring-loaded closing member controlling the connection with the unloading chamber and cooperating with a seat so that after exceeding of a predetermined pressure in the pressure chamber the connection of the pressure chamber to the unloading chamber is released. The closure part is composed of a synthetic plastic material and having a flange-like base body which closes the opening. The base body is provided with a depression and a pipe which is formed of one piece with the base body and extends into the depression to form the connection of the pressure chamber with the unloading chamber. An elastically deformable diaphragm which covers the depression for forming the pressure chamber and acts as a closing member cooperating with an end of the pipe as the seat. A separate holding element is mounted on the base body so that the diaphragm is clamped between the base body and the holding element.
