Abstract
The striking mechanism has a hammer barrel (), which has at least one control opening () through which, in an idle position, the air can escape from the hammer barrel (), and which in a striking position is closed by a covering () that prevents the escape of air. To achieve the greatest possible sealing off of the at least one control opening () and thus high efficiency of the striking mechanism, the covering () is molded from an elastomer.
