Patent ID: 6935286

Claim:
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 including a pressure region and an opening, comprising: a joining between the shaft end and the sleeve-shaped actuating element, the pressure region configured to be pressurized by a pressure medium, the sleeve-shaped actuating element configured to be guided in an axially movable manner within the pressure region, the sleeve-shaped actuating element further configured to at least partially surround the shaft end of the gas exchange valve, the joining being situated outside of the pressure region and in a region of the opening, and the joining being formed on a side of the valve actuator away from a combustion chamber; a through-hole configured to extend through the valve actuator to the region of the opening, wherein the opening is formed on an end away from the combustion chamber; wherein: the sleeve-shaped actuating element includes an actuator sleeve arranged to be guided in an axially movable manner through the through-hole, the actuator sleeve essentially extending from a bottom of the valve actuator into the region of the opening, the gas exchange valve includes a shaft inserted into the actuator sleeve from the bottom of the valve actuator, the shaft being surrounded by the actuator sleeve, the actuator sleeve includes integrally an end segment away from the combustion chamber, the end segment projecting out a distance from the opening of the valve actuator, the end segment including a coaxial bore hole formed therein, and the shaft end of the gas exchange valve is arranged to protrude into the coaxial bore hole and is connected with the end segment of the actuator sleeve.
