摘要: A fuel filter with a pressure regulating valve for fuel circulated from a fuel tank and injected into an internal combustion engine. The fuel filter comprises a filter pot closed by a cover and an annular filter element for radially filtering flow from the outside in. Fuel flows in and out through main flow connections on opposite sides of the filter. There is a recirculation connection to recirculate fuel. There is a pressure regulating valve on one end of the filter housing with the discharge connection. The pressure regulating valve operates against atmospheric pressure and has a spring-loaded diaphragm which acts in conjunction with a closure ram to close the inlet port of a recirculation flow duct which passes through the center of the filter and connects the regulating valve to the return connection. The diaphragm is fastened with the valve seat in a sealed manner to the edge of the pressure regulator housing, which open into the filter port and is formed in the cover of the filter housing. The return connection passes in a radially sealed manner through the center of an associated end disk of the filter element. The feed connection and the return connection are provided in a second end of the filter and the pressure regulating valve is connected to the return connection via a plug-in connection.
