| 20090004323 | Needle Valve Nozzle Assembly - The present invention relates to a manifold unit for supplying casting material in an injection moulding system for processing thermoplastic polymers via a hot runner system with at least one needle valve nozzle which can be sealed by a shut-off needle. In this case, the shut-off needle can be moved by a hydraulic or pneumatic drive system. The needle valve nozzle has a first longitudinal axis and the drive system, which has a piston, has a second longitudinal axis, the first longitudinal axis being arranged parallel to and laterally offset from the second longitudinal axis. | 01-01-2009 |
