Actuator device for sliding cam system of lifting cylinder combustion engine, has shift groove contacting with pin according extraction movement of pin and contact surface exhibiting cladding provided with hard-wearing layer

摘要

The device has an actuator pin (3) moving out from a housing, where the device is fastened to a component of a cylinder head or to the cylinder head of a combustion engine. A shift groove (7) of a sliding cam contacts with the actuator pin according extraction movement of the pin from the housing by a contact surface. The contact surface exhibits a contact cladding (6) e.g. spherical shaped cladding, with a hard-wearing layer i.e. diamond like-carbon layer.
