Abstract:
A device (10) comprising:a rigid rod (50) movable in straight line and a rotary motion and having one end which penetrates into an interior of a hollow portion (30b) of a piston (30), and which is fixed by means of a knuckle joint to the hollow portion (30b) of the piston (30) by one of a direct connection and an indirect connection through an interposed insert (60), said insert being accordingly mounted inside the hollow portion (30b) of the piston (30), and means (70) for axial immobilisation of one of the insert (60) and rod (50) with respect to the piston (30), wherein said immobilising means (70) includes an abutment (32) carried by the piston (30) to ensure axial immobilisation in a direction corresponding to a direction in which the rod is fitted in the piston, and a washer (72) carried by one of the insert (60) and rod (50), said washer (72) having radially elastically deformable peripheral lugs (76) which bear against an internal wall of the hollow portion (30b) of the piston (30) by deforming in order to ensure immobilisation of one of the insert and rod in an opposite direction.
