Swivel actuator device for lift control of a gas exchange valve in a
cylinder head of an internal combustion engine comprising a swivel motor
having a shaft on which is provided a first operating element having a
control path for opening the gas exchange valve, whereby a second
operating element having a second control path provided on the first
operating element. Due to the arrangement of the swivel actuator device,
less electric power is needed at low rotational speeds and processing of
the fuel mixture is improved.
