Abstract

An electrodynamic drive of a compact design is provided, particularly for a respiration system dispensing valve. The electrodynamic drive has a velocity measuring system that is uncoupled from the electrodynamic drive. The velocity measuring system is provided directly above a moving coil system, wherein the velocity measuring system has a short-circuit sleeve (15) for forming a separate magnetic circuit (221).
