PCT No. PCT/DE96/01136 Sec. 371 Date Apr. 15, 1997 Sec. 102(e) Date Apr. 15, 1997 PCT Filed Jun. 27, 1996 PCT Pub. No. WO97/13977 PCT Pub. Date Apr. 18, 1997An electromagnetically activated valve possesses an electromagnetic circuit, formed by, among other things, a magnetic coil, a magnet housing, and a core which serves as the inner pole. A valve element which serves as the anchor and closing element is spherical in structure, and moves axially within the magnet housing. A contact element is arranged between the core and the valve element, and has a contact surface with a spherical curve, facing the valve element. The valve element is surrounded by a guide element at least in part in the circumference direction, which element has a guide opening which also has a spherical curve, at least in part. The valve, in the form of a fuel injection valve, is particularly suitable for use in fuel injection systems for mixture-compressing, outside-ignition internal combustion engines.
