    摘要: A process for manufacturing an electromagnetically actuated fuel-injection valve with a connecting ring of a non-magnetic material hermetically and permanently installed between an internal pole and a valve sleeve designed separately from the internal pole. The process reduces the cost of manufacturing fuel-injection valves by avoiding costly operations involved in the fabrication and assembly of the highly precise individual structural elements and in producing the hermetic and permanent connections. A one-piece magnet body is formed with an internal pole and an outer valve sleeve joined by a base. Above the base, the internal pole and the valve sleeve are radially separated by an axially running ring opening. A solder member and a non-magnetic intermediate ring are inserted into the ring opening, and the intermediate ring is then soldered to the magnet body. The base is then removed, thereby separating the internal pole and the valve sleeve.
