Abstract

Distributeur pour moteurs hydrauliques. Ce distributeur est caractérisé par le fait qu'entre le corps de distribution en forme de plaque 13 et la paroi 24 du logement qui est perpendiculaire à l'axe de rotation 7 du moteur hydraulique associé, est inséré un élément 25, en forme de manchon tubulaire, dont le pourtour extérieur comporte au moins deux épaulements annulaires 26, 27 coopérant avec des épaulements annulaires correspondants 29, 30 de la paroi du logement, l'élément 25 étant fixé au logement par des moyens qui empêchent sa rotation, tout en lui permettant de se déplacer axialement Destiné notamment à être monté sur des moteurs hydrauliques du type à pistons radiaux.
