Definitions

an axially displaceable shut-off needle 30 is provided, which can be brought from an open position into two definable closed positions by means of a pneumatic drive 40.
a pneumatic drive 40 For this purpose, it lies concentrically in the melt channel 22 of the injection nozzle 20 and is connected at the end to a lifting plate 36 which is arranged by two pneumatic cylinders 42 of the drive 40 and their actuators 43 arranged symmetrically to the longitudinal axis L of the locking needle 30 can be raised and lowered evenly.
