The gas exchange valve arrangement for a super-charged piston engine comprises a gas exchange valve (1) having a valve head (2) and a valve stem (3), a valve guide (8), a valve spring (4), an air chamber (5), which is arranged in a cylinder head (9) around the valve guide (8), a piston (6), which is attached to the valve stem (3) and delimits the air chamber (5), and an air channel (7) for introducing pressurized charge air from an intake duct (10) into the air chamber (5). The piston (6) is arranged around the valve guide (8) and provided with a first seal (11), which is arranged be- tween the valve guide (8) and the inner perimeter of the piston (6) and with a second seal (12), which is arranged between the outer perimeter of the piston (6) and the wall of the air chamber (5). |
