PCT No. PCT/DE92/00727 Sec. 371 Date Apr. 14, 1993 Sec. 102(e) Date Apr. 14, 1993 PCT Filed Sep. 2, 1992 PCT Pub. No. WO93/06360 PCT Pub. Date Apr. 1, 1993.An electromagnetically operated injection valve including a return spring having upper and lower ends, the upper and lower spring ends are bent to extend axially and parallel with a valve's longitudinal axis. The upper end of the spring engages a recess of a fixed setting bushing, and the lower end engage in a recess of a needle sleeve so as to prevent twisting. Due to the position of a valve seat body relative to the valve closing member the same angle is maintained throughout the life of the assembly, the adaptation process of both components is reduced to a single running-in phase. The new injection valve is particularly suitable as an injection valve for fuel injection units of mixture compressing spark ignited internal combustion engines.
