  4. Mécanisme à came (10) selon la revendication 3, caractérisé en ce que le vecteur de force (FS) produit par la vis de serrage (20), qui correspond à peu près à celui de la force de pression (FP), est divisé respectivement en au moins un premier vecteur de triangle de forces (F1) qui s'étend perpendiculairement au plan de la surface de glissement (18) et en un second vecteur de triangle de forces (F2) qui s'étend dans le plan de la ou des surfaces de glissement (18) ou parallèlement à celles-ci.
  5. Mécanisme à came (10) selon l'une des revendications 1 à 4, caractérisé en ce que le dispositif de serrage (20) produit un serrage par poussée ou par traction.
  6. Mécanisme à came (10) selon l'une des revendications 1 à 5, caractérisé en ce qu'il est prévu plusieurs dispositifs de serrage (20) pour chaque surface de glissement (18).
  7. Mécanisme à came (10) selon l'une des revendications 1 à 6, caractérisé en ce que la position réglée du dispositif de serrage (20) est apte à être fixée par l'outil de travail.
  8. Mécanisme à came (10) selon l'une des revendications 3 à 7, caractérisé en ce que la position inclinée de la vis de serrage (20) bloque sans jeu la pièce d'ajustage de position de fin de course (26).
  9. Mécanisme à came (10) selon l'une des revendications 1 à 8, caractérisé en ce que les surfaces de glissement (18) présentent chacune une surface porteuse en métal fritté dans laquelle est inséré le lubrifiant solide.
  10. Mécanisme à came (10) selon l'une des revendications 1 à 9, caractérisé en ce qu'un dispositif de guidage en queue d'aronde ou à prisme est disposé entre le coulisseau (14) et le logement d'élément coulissant (12).
