    摘要: A process for the production of an injection nozzle comprising an essentially tubular inner part (16) and at least one essentially wire-type heating element (14, 15) which is embedded entirely inside a solid metal body (12, 13) lying in a close-fitting manner around the inner part in which one or more separate, essentially tubular metal bodies (12, 13) with a heating element (14, 15) embedded therein are formed by placing the heating element and the metal in a molten state in a mold, so that the heating element is completely enclosed by the molten metal, and subsequently allowing the metal to set, following which the body thus formed is removed from the mold and this tubular body or these tubular bodies thus obtained is or are then slid over the tubular inner part up to a certain point. Advantageously, a fully open axially running slit (12', 13') is formed in the wall of the tubular body (12, 13), while the wire-type heating element (14, 15) extends in curved loops running zigzag through the body and extending to the slit.

    摘要: The invention relates to a drive system provided with a cylinder shell with two end sections and, inside said cylinder shell, a central combustion chamber with two piston bodies arranged therein, that are displaceable in axially opposed directions within said combustion chamber, wherein a drive rod extending along the longitudinal axis of the cylinder shell is connected with each piston body and has a drive extension extending outwardly from each respective end section of said cylinder shell, wherein said drive rods are each connected via a drive element with a rotary body that can rotate around the cylinder shell, wherein said drive elements are provided with bearings that bear upon said rotary body and that, when in reciprocating motion, drive said rotary body in rotation about said longitudinal axis.

    摘要: Known apparatuses to inject liquids, in particular plastics into injection moulds have closure rods which remain in the gating when the closure system is opened. In the present apparatus the liquid passage always is completely free when the closure system is opened, because the closure rod can be totally retracted from the liquid passage. This can be accomplished in two ways: either the liquid passage extends in a bended manner or the closure rod has a side view in the configuration of a sector or a circle.
