Abstract

L'invention concerne un bras destiné à être utilisé dans un mécanisme de liaison transformant un mouvement rectiligne en mouvement de rotation, un mécanisme de liaison et un élément de pompe comprenant un tel bras, et une pompe à combustible comprenant un tel mécanisme de liaison. Le bras présente une extrémité profilée qui comporte deux parties incurvées agencées pour venir en contact, pendant le fonctionnement, avec des parties opposées respectives de l'élément à mouvement rectiligne, chacune des parties incurvées ayant un profil qui est sensiblement défini par la courbe décrite par une extrémité respective d'une droite de longueur fixe lorsque cette droite tourne autour d'un premier point d'une première position à une seconde position, et continue à tourner dans le même sens autour d'un second point d'une seconde position à une troisième position, le second point étant écarté du premier point. Application à la commande de la position angulaire des pistons dans une pompe en ligne.The invention relates to an arm for use in a link mechanism transforming a rectilinear movement into a rotational movement, a link mechanism and a pump member comprising such an arm, and a fuel pump comprising such a link mechanism. The arm has a contoured end which has two curved parts arranged to come into contact, during operation, with respective opposing parts of the rectilinearly moving member, each of the curved parts having a profile which is substantially defined by the curve described by a respective end of a straight line of fixed length when this straight line rotates around a first point from a first position to a second position, and continues to rotate in the same direction around a second point from a second position to a third position, the second point being separated from the first point. Application to the control of the angular position of the pistons in an in-line pump.
