Abstract

Die Erfindung betrifft ein Eintreibgerät, umfassend einen Tank (2) zur Speicherung eines Brennstoffs, insbesondere Flüssiggas, eine mit dem Tank (2) verbundene Brennkammer (1), wobei die Brennkammer (1) einen beweglichen Kolben (6) zum Antrieb eines Eintreibstößels (7) aufweist, und eine zwischen dem Tank (2) und der Brennkammer (1) angeordnete Dosiervorrichtung (4), wobei die Dosiervorrichtung (4) ein bewegbares Verdrängerglied (19) zum Ausstoßen des Brennstoffs aus einem Dosiervolumen (15) aufweist, wobei das Verdrängerglied (19) durch eine Betätigungskraft aus einer ersten Kraftquelle in einer Verdrängungsrichtung gegen einen Druck des Brennstoffs bewegbar ist, wobei an dem Verdrängerglied (19) eine zusätzliche Stützkraft aus einer zweiten Kraftquelle angreift.
