Abstract

Ein Elektrohandwerkzeuggerät zur Erzeugung einer zumindest teilweise schlagenden Bewegung eines Werkzeugs (6) mit einem pneumatischen Schlagwerk mit einer Gasfeder (1) in einem Führungsrohr (2) und einer Leerschlagabschaltung des Schlages bei fehlendem axialen Gegendruck über das Werkzeug (6), wobei sich im Falle des Leerschlags ein Flugkolben (4) und ein Döpper (5) in einer Leerschlagposition befindet, welche über einen, über Ventilöffnungen (8) steuerbaren, geöffneten, sich axial ausserhalb des Innenmantels des Führungsrohrs (2) erstreckenden, Luftkanal (9) die Belüftung der Gasfeder (1) zur Umgebung ermöglicht, wobei sich der Luftkanal (9) vom axialen Bereich der Gasfeder (1) bis zum axialen Bereich des Döppers (5) erstreckt und die Ventilöffnungen (8) zur Belüftung der Gasfeder (1) durch den in einer Arbeitsposition angeordneten Döpper (5) verschliessbar sind.
