ABSTRACT:
An injection device is disclosed for the treatment of wood without the necessity of a rivet-set. The injection device has a deformable elastic body having an internal cavity intended to receive a conical injection head and including an anti-return valve system therein. The upper part of the body has a double wall which consists of an external wall and an internal wall. The external wall absorbs deformations due to the driving-in phase of the injection device. The internal wall insures the nondeformation of the circular ridge of the cavity to guarantee the seal between the conical injection head and the injection device during the injection phase of the treatment product.
