摘要

The cylinder head has cross-section adjusting device upstream and downstream of the recess (4). The cross-section adjusting device is regulated by two movable elements (5,6). The element (5) is brought into end position from a starting position, in which the channel (2) is not affected. The element (5) protrudes in the channel in the end position and partially closes this. Another element (6) is coupled to the element (5) and protrudes from element (5) into the channel.
