  • Injection nozzle for plastic substances
    Patent number: 6506045
    Abstract: A nozzle, for the injection of molten plastics, includes a rear central portion terminating with a planar surface, and an outer annular element terminating with a corresponding planar surface on its rear side. The terminal planar surface of the central portion is situated in a more rearward position relative to the planar surface of the outer annular element. A first annular groove forms an acute angle between the outer edge of the rear portion and an inner surface of the outer annular element. A second annular groove, forming an acute angle, is provided in the rear portion. The two annular grooves open in opposite directions, and the bottoms of the respective grooves are located at substantially the same height of the nozzle.
