November 14, 2001
The injection valve has a pre-loaded longitudinally elastic sleeve-shaped element (35,37) to charge a valve member (10) in closing direction. The sleeve element is rotary-symmetrical, and is e.g. bellows-shaped. The bellows consist of truncated cone-shaped parts of different heights, with facing edges being rounded.
