A fluid power transfer device (20) includes a wobble plate assembly (26) having a wobble plate (58) that rolls against truncated cone portions (42) of a housing (22) and has an inner extremity 60) rotatably supported by an axially inclined annular bearing (49), 49') on a spherical member (46) of the wobble plate assembly so as to rotate a shaft (24) during the wobbling motion. One embodiment includes a journal bearing (49) and an oil lubrication system (114) and another embodiment includes antifriction roller bearings (220) that support the wobble plate (58) on the spherical member (46), antifriction roller bearings (224) that rotatively support the shaft (24) on the housing (22') and seals (226) that rotatively seal between the shaft (24) and the housing (22'). The fluid power transfer device can be used as an internal combustion engine, a heat engine, a pump, a compressor or a fluid motor.

La présente invention concerne un dispositif de transfert d'énergie hydraulique (20) comportant un ensemble de plateau oscillant (26) ayant un plateau oscillant (58) qui roule contre des portions de cônes tronconiques (42) d'un boîtier (22) et présente une extrémité interne (60) supportée en rotation par un roulement radial (49), (49') d'un organe de forme sphérique (46) de l'ensemble de plateau oscillant afin de faire tourner un arbre (24) au cours du mouvement d'oscillation. Un mode de réalisation comprend une portée de tourillon (49) et un système de lubrification à l'huile (114) et un autre mode de réalisation comprend des paliers à roulement (220) qui maintiennent le plateau oscillant (58) sur l'organe de forme sphérique (46), les paliers à roulement (224) qui maintiennent en rotation l'arbre (24) sur le boîtier (22') et des joints (226) qui réalisent une étanchéité rotative entre l'arbre (24) et le boîtier (22'). Le dispositif de transfert d'énergie hydraulique peut être utilisé dans un moteur à combustion interne, un moteur thermique, une pompe, un compresseur ou un moteur hydraulique.
