Abstract

The present invention relates to a connection between a shaft end of a gas exchange valve of an internal combustion engine and a sleeve-shaped actuating element of a valve actuator, which is guided in an axially movable manner within a pressure region, which is able to be pressurized with a pressure medium, of the valve actuator and at least partially surrounds the shaft end. The present invention provides for the connection to be situated outside of the pressure region and in the region of an opening, which is formed on the side of the valve actuator away from the combustion chamber, and is, for example, coaxial to the shaft end.
