Abstract
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.
Claims12
A swivel actuator device for control of an internal combustion engine valve, comprising:
- a swivel motor with a swivel shaft;
- a first operating element with a first control path disposed on the swivel shaft;
- a second operating element with a second control path disposed on the first operating element,
- wherein the first operating element and the second operating element swivel about a common axis,
- wherein the first control path is subdivided into at least a first zero lift range and a first lift range, and the second control path is subdivided into at least a second zero lift range and a second lift range, and
- wherein the first control path has a full lift range, the second control path has a partial lift range, or the first control path has a full lift range and the second control path has a partial lift range.
