Abstract

Die Einspritzvorrichtung gemäß der vorliegenden Erfindung umfasst eine Förderschnecke (1), die vertikal angeordnet ist, einen zum Vorschieben/Zurückziehen der Förderschnecke vorgesehenen Wechselstrom Servomotor (41) zur Erzeugung eines Drehmoments durch Drehung eines Rotors (412) und eine Einheit (42) zur Umwandlung einer Antriebskraft zur Umwandlung des Drehmoments in eine lineare Antriebskraft zur Bewegung der Förderschnecke (1) in der vertikalen Richtung, wobei der Wechselstrom Servomotor (41) eine erste Bremseinheit zum Halten des Rotors (412) in einer Ruhestellung umfasst. Durch Betätigung der ersten Bremseinheit kann eine Bewegung der Förderschnecke (1) in der vertikalen Richtung aufgrund ihres Eigengewichts verhindert werden.
