DEVICE FOR INJECTING A LIQUID PRODUCT COMPRISING TWO HALF-SHELLS ROTATABLY MOBILE RELATIVE TO EACH OTHER.

摘要

The present invention concerns a device for injecting a liquid product contained in a bag, the device comprising a housing consisting of two half-shells (21, 22) articulated about an axis of rotation in order to allow the relative movement of the half-shells relative to each other between: - an open position in order to put the bag in place and - a closed position for injecting the liquid product contained in the bag, remarkable in that: - one of the half-shells comprises a deformable bladder (23) - called the "active bladder" - having a volume that varies under the action of a hydraulic ram supplying said bladder with hydraulic fluid, and - the other of the half-shells comprises a deformable damping cushion (24) having a constant volume - called the "passive cushion".
