Title (EN) A RADIAL PISTON MOTOR OR PUMP
(FR) MOTEUR OU POMPE A PISTONS RADIAUX
Abstract:
(EN) A motor or pump assembly (1) comprises a cylinder block (4) with a plurality of radially positioned cylinders (3), a piston (2) arranged slidably reciprocable in each of the cylinders, a cam ring (7) cooperating with the pistons and being rotatably journalled on the cylinder block, and a distributor valve (9) arranged centrally in the cylinder block to control a flow of fluid to and from the cylinders in operation. The cam ring (7) is journalled on the cylinder block (4) with at least one ball bearing with balls (25) arranged on each side of the cylinder block. These balls run in grooves which are positioned close to the sides and periphery of the disc-shaped cylinder block. This provides a structure which has a very small axial length and which is simultaneously capable of absorbing great loads both radially and laterally.
(FR) Un moteur ou une pompe (1) comprend un bloc (4) équipé de plusieurs cylindres disposés radialement (3), un piston à mouvement alternatif (2) disposé de façon coulissante dans chacun des cylindres, un anneau à came (7) coopérant avec les pistons et monté en tourillon de manière rotative sur le bloc, et une soupape de distribution (9) disposée de façon centrale dans le bloc pour commander le débit de fluide vers et depuis les cylindres pendant le fonctionnement. L'anneau à came (7) est monté en tourillon sur le bloc (4) à l'aide d'au moins un palier à billes dont les billes (25) sont disposées de chaque côté du bloc. Lesdites billes se déplacent dans des rainures positionnées près des côtés et de la périphérie du bloc en forme de disque. On obtient ainsi une structure d'une longueur axiale faible qui est capable d'absorber simultanément des charges radiales et latérales importantes.
