Abstract

Das erfindungsgemässe pneumatische Schlagwerk beinhaltet einen Führungszylinder, indem ein Flugkolben und ein Erregerkolben längs einer Schlagachse beweglich angeordnet sind. Der Führungszylinder weist einen Kunststoff auf. Ein pneumatischer Raum, abgeschlossen durch den Führungszylinder, den Flugkolben und den Erregerkolben, und ein Antrieb zum periodischen Bewegen des Erregerkolbens, wodurch der Flugkolben zu einer periodischen Bewegung zwischen Schlagfläche und Erregerkolben angeregt ist, sind in dem Schlagwerk vorgesehen.
