Title: VALVE FOR METERING A FLUID, CONNECTION PIECE FOR A VALVE, AND FUEL INJECTION SYSTEM
Abstract:
The invention relates to a connection piece (3) for a valve (2), which valve is used to meter a fluid, comprising a sealing section (19), on which at least one annular sealing element (22) is arranged. The annular sealing element (22) circumferentially surrounds the sealing section (19) with respect to a longitudinal axis (18). Furthermore, the annular sealing element (22) is supported by means of a supporting ring (23) on an end (31) of the sealing section (19). The sealing section (19) has a circumference that increases along the longitudinal axis (18) at least in a region (19') along the longitudinal axis (18) in which the annular sealing element (22) surrounds the sealing section (19).
