Title
(EN) DISPLACEMENT ASSEMBLY FOR A FLUID DEVICE
(FR) ENSEMBLE DE DÉPLACEMENT POUR UN DISPOSITIF HYDRAULIQUE
Abstract
(EN) A displacement assembly includes a rotor and a plurality of reciprocating members in engagement with the rotor. The displacement assembly further includes a ring assembly. The ring assembly defines a cam surface that is in engagement with the reciprocating members. The ring assembly has a first ring and an axially adjacent second ring with at least one of the first and second rings being adapted for selective movement relative to the other between a neutral position and a displaced position. The first ring has a first ring portion defining a bore that has an inner surface. The second ring has a second ring portion defining a bore that has an inner surface. A first circumferential portion of the inner surface of the first ring portion and a second circumferential portion of the inner surface of the second ring portion define the cam surface in the displaced position.
(FR) Un ensemble de déplacement comprend un rotor et une pluralité d'éléments animés d'un mouvement alternatif en prise avec le rotor. L'ensemble de déplacement comprend en outre un ensemble de bagues. L'ensemble de bagues définit une surface de came en prise avec les éléments animés d'un mouvement alternatif. L'ensemble de bagues comprend une première bague et une seconde bague axialement adjacente, au moins l'une des première et seconde bagues étant adaptée au mouvement sélectif par rapport à l'autre bague entre une position neutre et une position déplacée. La première bague comprend une première partie de bague définissant un trou qui présente une surface interne. La seconde bague comprend une seconde partie de bague définissant un trou qui présente une surface interne. Une première partie circonférentielle de la surface interne de la première partie de bague et une seconde partie circonférentielle de la surface interne de la seconde partie de bague définissent la surface de came dans la position déplacée.
