Abstract

L'invention concerne un bras pivotant dans une tête d'entraînement d'une pompe à seringue pour le support d'un piston de seringue. Le bras comprend un premier élément en métal, définissant l'axe de pivotement, un élément pour le support du piston de seringue (deuxième élément) en matière plastique, et un troisième élément, en forme de broche, pour la liaison du premier élément avec le deuxième élément, et pour le renforcement du deuxième élément, le deuxième élément étant solidement relié aux premier et troisième éléments par surmoulage sur ces derniers.
