Abstract
The invention relates to an injection device comprising a syringe body ( ), which delimits a chamber which is designed to be filled with liquid, and a unit ( ) for distributing the liquid, comprising an end piece for closing off the said chamber, which is extended by a base, which supports an injection needle which is protected by a protective cap ( ), the said distribution unit being mobile axially between a closing-off position of the chamber, and a position for injection of the liquid. According to the invention, the unit ( ) for distributing comprises an intermediate section ( ) between the base and the closing-off end piece, and the syringe body ( ) comprises a ring ( ) which delimits two superimposed compartments ( ), which can each accommodate the said intermediate section. In addition, the protective cap ( ) and this intermediate section ( ) have complementary profiles ( ) in the form of a cam, which can permit generation of axial displacement of the unit ( ) for distributing, towards its injection position, during rotation of the said protective cap.
