    Abstract: A system is disclosed for driving an actuator which comprises a chamber, a shutter of an injection nozzle for molten material for injection molding, and a piston translatable inside the chamber to actuate a shutter. Means are provided for the transfer of a predetermined amount of fluid between the outside and inside of the chamber, so as to bring/move the shutter from a closing position, in which there is no passage of molten material, towards an opening position, in which there is passage of molten material, by injecting the predetermined amount of fluid from the outside into the chamber or by injecting the predetermined amount of fluid from the chamber towards the outside, or vice versa.

    Abstract: An injection apparatus for injecting molten plastic into a mold of articles made of thermoplastic material including bottle preforms. The injection apparatus includes an injection nozzle and a shutter for controlling flow of the molten plastic through the injection nozzle. A cylinder-piston system moves the shutter from open and closed positions of the injection nozzle. The cylinder-piston system includes a first chamber with a first passage for introducing fluid into the first chamber to open the shutter, and a second passage, different from the first passage, for discharge of fluid and of possible particles from the first chamber. A fluid distribution device with a first channel is connected to the first passage, and a second channel different from the first channel is connected to the second passage. The cylinder-piston system includes a second chamber having a third passage for introducing fluid into the second chamber to close the shutter.

    Abstract: A linear actuator for use in an injection molding apparatus is provided. The linear actuator comprises an electric motor including a drive shaft; an anti-rotation mechanism including a restrictor and a captive member, the captive member attached to the pin, the restrictor and the captive member arranged for translating a rotational motion of the drive shaft to a linear motion of the captive member, and by extension the pin, relative to the restrictor; and an adapter coupling the drive shaft with the captive member to enable the drive shaft to transmit the rotational motion of the drive shaft and to be readily decoupleable from the captive member without needing to separate the captive member from the pin.
