A valve assembly for a fuel pump and comprising: a one-way outlet closing valve , which only allows fuel to flow out; a one-way pressure relief valve , which only allows fuel to flow in; a connector , which has a housing on the inside; a valve disc , which engages the housing of the connector and has a plurality of through outlet holes , which are part of the outlet closing valve and are each provided with a first valve seat obtained in the area of a first wall of the valve disc , and a through relief hole , which is part of the pressure relief valve and is provided with a second valve seat obtained in the area of a second wall of the valve disc parallel to and opposite the first wall ; an annular body , which is arranged in the housing of the connector , engages the housing without clearance and has a central through hole with a cylindrical shape, which allows fuel to axially flow towards the valve disc ; a spring , which is part of the pressure relief valve , is arranged in the central hole of the annular body and pushes a shutter of the pressure relief valve against the second valve seat ; a striker body , which is cup-shaped so as to contain, on the inside, one end of the spring , has a centrally perforated base wall, against which the spring rests, is arranged in the central hole of the annular body and is fixed inside the annular body ; and a connection element , which is interposed between the shutter of the pressure relief valve and the spring ; the valve assembly is characterized in that the central hole of the annular body has an annular protuberance , which projects from a wall of the central hole and constitutes a limit stop that limits the travel of the connection element . a one-way outlet closing valve , which only allows fuel to flow out; a one-way pressure relief valve , which only allows fuel to flow in; a connector , which has a housing on the inside; a valve disc , which engages the housing of the connector and has a plurality of through outlet holes , which are part of the outlet closing valve and are each provided with a first valve seat obtained in the area of a first wall of the valve disc , and a through relief hole , which is part of the pressure relief valve and is provided with a second valve seat obtained in the area of a second wall of the valve disc parallel to and opposite the first wall ; an annular body , which is arranged in the housing of the connector , engages the housing without clearance and has a central through hole with a cylindrical shape, which allows fuel to axially flow towards the valve disc ; a spring , which is part of the pressure relief valve , is arranged in the central hole of the annular body and pushes a shutter of the pressure relief valve against the second valve seat ; a striker body , which is cup-shaped so as to contain, on the inside, one end of the spring , has a centrally perforated base wall, against which the spring rests, is arranged in the central hole of the annular body and is fixed inside the annular body ; and a connection element , which is interposed between the shutter of the pressure relief valve and the spring ; the valve assembly is characterized in that the central hole of the annular body has an annular protuberance , which projects from a wall of the central hole and constitutes a limit stop that limits the travel of the connection element . <EOS>
