Abstract
A valve control device for controlling the stroke of a valve of a combustion engine includes: a first body part and a second body part, co-axially arranged, rotatably arranged relative to each other and axially displaceable between a first axial relative position and a second axial relative position; a spring for urging the first body part and the second body part away from each other; wherein the first and second body part have both axial surfaces facing each other and provided with cams evenly distributed along the circumference of the axial surface and wherein the pitch of the cams on both axial surfaces is equal; and a locking pin arranged in axial direction through the first body and extending on both sides, wherein one end of the locking pin extends through a cam.

A valve control device for controlling stroke of a valve of a combustion engine, the device comprising:
- a first body part and a second body part, co-axially arranged, rotatably arranged relative to each other, and axially displaceable between a first axial relative position and a second axial relative position;
- a spring configured to urge the first body part and the second body part away from each other;
- wherein the first and second body part each have a respective axial surface facing each other,
- wherein the first and second body parts include cams evenly distributed along a circumference of the respective axial surface,
- wherein a pitch of the cams on both axial surfaces is equal, and
- wherein a locking pin is arranged in an axial direction through the first body part and extending on both sides thereof, one end of the locking pin extending through a first cam of the cams.
