Abstract

La présente invention concerne un mécanisme à plateau oscillant, en particulier pour des pompes à pistons axiaux. Ce mécanisme comprend un corps oscillant (7, 13) qui est monté de manière à pouvoir tourner autour d'un axe de rotation (3) de manière inclinée par rapport à celui-ci et qui vient s'appuyer dans un boîtier (1) par l'intermédiaire d'un roulement radial, ainsi qu'un plateau oscillant (10) qui est monté rotatif sur le corps oscillant, avec un roulement axial interposé, et sur lequel des éléments menés (12) qui oscillent sur la face sont montés sur ressorts. Selon cette invention, le roulement radial et/ou le roulement axial sont conçus sous forme de roulement à fils (8, 9, 14, 15).
