The invention refers to a valve device for a combustion engine which includes a combustion chamber (1) and at least one channel (5) for communication between the combustion chamber (1) and an external space. The valve device includes a rotatable valve body (13), which is provided in said channel (5) and includes a passage (14) extending in a direction through said valve body (13). The valve body (13), which is rotatable around an axis of rotation forming an angle to the direction (p) of said passage (14), is arranged to open and close, respectively, said channel (5) by means of said passage (14) by rotation, a rotary motor (16) separated from the combustion engine is provided.

1. A valve device for a combustion engine including a combustion chamber and at least one channel for communication between the combustion chamber and an external space, the valve device comprising:a rotatable valve body which is provided in said channel, said valve body including a passage extending in a direction through the valve body, the valve body being rotatable around an axis of rotation forming an angle to the direction of said passage which is arranged to form an open position and a closed position of said channel by rotation in one rotary direction around said axis of rotation; and a rotary motor separate from the combustion engine and arranged to provide said rotation, wherein the rotary motor is arranged to rotate said valve body from one of said positions to an adjacent of said positions by a first high rotation velocity, to rotate said valve body in this adjacent position by a second rotation velocity at a relatively lower rotation rate than said first high rotation velocity, and thereafter to rotate said valve body from said adjacent position to the next adjacent positions by the first high rotation velocity.
