Abstract

The exhaust gas return valve for an internal combustion motor has a component (6) which stores kinetic energy. It acts on the head (13) on the free end of the valve stem (9). The component (6) is the armature of an electromagnet which, in the rest position, is held clear of the valve stem head (13) by a spring.
