Connection between two shaft ends in an internal combustion engine air exchanging valve and a valve actuator

The present invention relates to a connection between two shaft ends (8, 10), situated coaxially one behind the other, of a gas exchange valve (1) of an internal combustion engine and a piston rod (2) of a valve actuator (4), where at least one coupling member (14) at least partially surrounds the shaft ends (8, 10). The present invention provides for the coupling body (14) to be radially tensioned with respect to the two shaft ends (8, 10) by at least one tensioning member (34, 36) to produce static friction locking between each shaft end (8, 10) and the coupling member (14) that transfers the actuating motion of valve actuator (4) to gas exchange valve (1) in a slip-free manner. As a result, the fatigue strength of the connection is able to be increased and its assembly and disassembly is simplified.
