Piezoelectric control block

摘要

A piezoelectric control block, particularly for controlling a fuel injection device for a combustion engine, preferably diesel engine, with a distributor injecting pipe, has an adjustable fuel quantity adjusting member, and a longitudinally extending mechanical movement converter which is formed so that under longitudinal load it deforms transversely to its longitudinal expansion and has a part which performs an overproportional movement under the longitudinal load and is connected with the feed quantity adjusting member.
