Publication number: 20220032522Abstract: The invention relates to a system for controlling a shutter (110) slidably arranged in a plastic material injection nozzle (11), comprising a rotary electric motor (M) and a mechanism adapted to couple said motor (M) to the shutter to slidably drive it between a closing position of the nozzle and a maximum opening position of the nozzle, characterised in that said mechanism comprises: an eccentric (21) integral with an output shaft (20) of the motor so as to be rotationally driven by said output shaft, comprising a crank pin (22) parallel to the output shaft but non-coaxial with said shaft (20), a slide (23) adapted to be made integral with one end of the shutter (110), and a connecting rod (25), a first end of which is articulated on the crank pin (22) of the eccentric (21) and a second end is articulated on an axis (25b) of the slide (23) such that the rotation of the eccentric causes sliding of the oscillating shutter between the closing position and the maximum opening position.Type: ApplicationFiled: November 27, 2019Publication date: February 3, 2022Applicant: RUNIPSYS EUROPEInventor: Eric DERICHE

Patent number: 8375579Abstract: The disclosure relates to a system for injecting a thermoplastic material in the fluid state, including: a dispenser adapted to be maintained at an injection temperature higher than the temperature limit at which the material is in a fluid state; an injection nozzle defining at least one portion of a transition passage; a stopper mounted inside the transition passage so as to slide between a blocking position and an opening position thereof; and control means for alternately sliding the stopper, wherein the control means comprises a jack with a rod parallel to the sliding direction of the stopper, and which is secured in an offset manner on the dispenser via a flattened beam, and a lever arranged so as to tilt about an axis so as to transmit the movements of the jack rod to the stopper.Type: GrantFiled: December 7, 2009Date of Patent: February 19, 2013Assignee: Runipsys EuropeInventor: Eric Deriche
