Abstract (en)

[origin: DE10128611A1] The ejector device has an ejector ram (11) with thread (12), which is moved axially towards the cartridge mouth (6) by an end piece with inner thread screwed into the rear cartridge end. The ejector ram has an inner ram part (16) charging the piston (9) sealing the inner chamber (2), and a concentric tubular outer ram part (17), charging the ring-shaped piston (10) loading the outer chamber (3). The ejector ram thread extends across the complete length of the outer ram part, and the end piece is formed as a threaded ring (13). The ejector ram is a one-piece injection-molded plastic part.
