Zusammenfassung:	A valve assembly (7) for a fuel pump (1) and having: a one-way outlet closing valve (8), which only allows fuel to flow out; a one-way pressure relief valve (9), which only allows fuel to flow in; a connector (11), which has a housing (13) on the inside; a valve disc (14), which engages the housing (13) of the connector (11) and has a plurality of through outlet holes (18) and a through relief hole (20); an annular body (33) which is arranged in the housing (13) of the connector (11) and has a central through hole (34); a spring (30), which is part of the pressure relief valve (9), is arranged in the central hole (34) of the annular body (33) and pushes a shutter (29) of the pressure relief valve (9); and a connection element (31) interposed between the shutter (29) of the pressure relief valve (9) and the spring (30). The central hole (34) of the annular body (33) has an annular protuberance (40) which constitutes a limit stop that limits the travel of the connection element (31).
