Two-stage magnet valve of compact design for an injector of an injection system for internal combustion engines

In an injector for an injection system for internal combustion engines, having a magnet valve (15) which controls the outflow of fuel (3) from a valve control chamber (11) through an outflow conduit (12), in which the magnet valve (15) has means (41, 47) for closing the outflow conduit (12), an armature (43) that is actuatable by an electromagnet (49) and is operatively connected to the means (41, 47) for closing the outflow conduit (12), a first valve spring (45) and a second valve spring (57) and a first stroke stop (61), the improvement wherein the first valve spring (45) urges the armature (43) in the closing direction with a greater spring force, and from the closing position of the magnet valve (15) until the first stroke stop (61) is reached, the second valve spring (57) urges the armature (43) in the opening direction with a lesser spring force, wherein the second valve spring (57) acts upon the armature (43) via a displaceable intermediate ring (59), and that the travel of the intermediate ring (59) is limited by the first stroke stop (61).
