Abstract
A device having a rigid rod mobile in a translational and/or rotational movement, whereof one end penetrates inside a recess of a piston and is fixed by a swivel to the recess of the piston directly or via an insert. The insert is mounted inside the recess of the piston, with a mechanism for axially locking the rod or the insert relative to the piston. The locking mechanism includes a stop borne by the piston to provide axial locking along a direction corresponding to the mounting direction of the rod in the piston, and a washer borne by the insert or the rod. The washer has peripheral fins elastically deformable in the radial direction and is pressed against the inner wall of the recess of the piston by being deformed to lock the insert or the rod in the opposite direction.
Claims15
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.
