Electromagnetically actuatable fuel injection valve

Claim 1

In an electromagnetically actuable fuel injection valve (1) having a valve housing (3), a valve seat body (5) provided with a bore (7) and a valve seat (9); a valve closing element (10) extending into the bore (7) to cooperate with the valve seat (9) and carrying an armature (15) on end end of the valve closing element (10) furthest from the vavle seat (9); a compression spring (29) positioned to act on the armature (15) and urge the armature in a direction toward the valve seat (9) and an inner pole (31) of a magnetic coil (33) having a stop face (16) said inner pole (31) being positioned so that the stop face (16) is opposite to the armature (15), the improvement comprising a lift-limiting plate (21) arranged between the armature (15) and the stop face (16) and a bearing plate (27) located between the lift-limiting plate (21) and the compression spring (29) acted on by the compression spring (29), and wherein the lift-limiting plate (21) includes a curved receiving surface (23) and a peripheral outer plane annular face (22) connected with the curved receiving surface (23), the bearing plate (27) having a curved pressing surface (25) shaped to fit the curved receiving surface (23) in which the bearing plate (27) is seated under action of the compression spring (29), and wherein the peripheral outer plane annular face (22) is located opposite the stop face (16), and the lifting-limiting plate has a curved bearing surface (19) which fits a correspondingly curved bearing surface (17) of the armature (15) so that the lift-limiting plate (21) is supported with the curved bearing surface (19) engaged in the correspondingly curved bearing surface (17) of the armature.
