A fuel injection valve with a valve needle of a narrow guidance play of the valve needle and the guide opening of the valve housing are improved by two guide sections of the valve needle being guided by guide balls which are seated against conical faces adjacent to the two guide sections. The balls are pressed against the conical faces by use of a compression spring. BUTTERFLY VALVESThe fuel injection valve is particularly suited for injecting fuel into mixture compressing internal combustion engines with externally supplied ignition. A fuel injection valve for internal combustion engines, comprising a valve housing, Needle Valvessaid valve housing including a longitudinal valve axis, with a longitudinal opening extending along the longitudinal valve axis in the valve housing, a valve needle, said valve needle includes a first guide section and a second guide section for axially guiding the valve needle along the longitudinal valve axis in the valve housing, a sealing seat on the valve needle, Plug Valves said sealing seat is disposed downstream of the second guide section and cooperates with a valve seat face on a valve seat body, a plurality of first balls engage a circumference of the first guide section and a plurality of second balls engage the circumference of the second guide section in order to guide the valve needle along said valve axis, and the plurality of first balls rest against the first guide section at a first conical face of a guide ring and the second balls rest against the second guide section at a second conical face on the valve seat body. The fuel injection valve according to the invention has the advantage over the prior art that a play-free guidance of the valve needle can be easily achieved in which very low friction forces occur and the leakproofness of the valve is assured over long operating times. Advantageous improvements and updates of the fuel injection valve include first balls that engage a circumference of a first guide section and second balls that engage a second guide section in order to guide the piston. It is particularly advantageous to permit the first balls on the first guide section to rest against a first conical face and to permit the second balls on the second guide section to rest against a second conical face, which in a reasonably priced manner produces a precision guidance by means of geometrically simple parts. It is likewise advantageous to embody the valve seat face flush with the second conical face and to provide it on a valve seat body that is fastened to the valve housing so that the machining is simplified. It is furthermore advantageous to act upon the first balls and the second balls by means of a compression spring so that through the contact of the balls against the conical faces, a radial force component of the balls against the valve needle is produced, which assures a play-free guidance. The invention will be better understood and further objects and advantages thereof will become more apparent from the ensuing detailed description of preferred embodiments taken in conjunction with the drawing.
