The invention relates to a hydrodynamic machine – comprising a bladed primary wheel that can be driven by a rotary shaft and a bladed secondary wheel, which together form a work chamber that can be filled or is filled with a working medium; - with a dynamic pressure pump for at least indirectly delivering working medium from the work chamber or from the hydrodynamic machine, wherein - the dynamic pressure pump has a first working medium inlet, which projects into the work chamber or an adjacent chamber that is connected in a working medium conducting manner, and has a first inlet opening which is aligned with the rotary shaft in the circumferential direction; and - the dynamic pressure pump has a second working medium inlet, which projects into the work chamber or an adjacent chamber that is connected in a working medium conducting manner, and has a second inlet opening which is aligned to the rotary shaft in the circumferential direction opposite to the first inlet opening; wherein - the first working medium inlet and the second working medium inlet are joined in a working medium conducting manner to a common working medium channel behind the two inlet openings. The hydrodynamic machine according to the invention is characterized in that the first working medium inlet and the second working medium inlet extend adjacent to each other in the same direction in the flow direction of the working medium, seen from the common working medium channel, separated by a separation wall.

The invention relates to a starting element (30) for using in drive systems, especially drive systems of motor vehicles, comprising a hydraulic coupling (2.3) and a lock-up coupling (3.3) which are connected in parallel. According to the invention, the drive sides of the lock-up coupling (3.3) and the hydraulic coupling (2.3) are interconnected in a rotationally-fixed manner. The hydraulic coupling (2.3) can be engaged and disengaged, a first state comprising the emptying of a toroidal working chamber (6.3) and a second state comprising the filling of said chamber. The activation of the lock-up coupling (3.3) triggers the emptying of the toroidal working chamber (6.3).

A bearing assembly comprises an outer bearing member having a cylindrical bore therethrough and a cylindrical inner bearing member extending coaxially within the bore in the outer bearing member, the inner bearing member having a cylindrical bore therethrough for accepting a rotating shaft. A first conduit is provided for supplying fluid to the bore in the outer bearing member to form a hydrostatic bearing between the inner bearing member and the outer bearing member, the first conduit comprising a passageway through the inner bearing member having four openings into the bore in the outer bearing member, the openings being arranged into pairs, the openings in each pair being in opposing regions of the bore. A second conduit is provided for independently supplying fluid to the bore in the inner bearing member to form a hydrodynamic bearing between the inner bearing member and a shaft located in the bore in the inner bearing member, the second conduit comprising a passageway having two openings into the bore in the inner bearing member, the openings being in opposing regions of the bore.

摘要:
Il s'agit d'un coupleur hydrocinétique comportant une chambre de retardement (20), qui s'étend dans un volume hors tout radialement inférieur à celui de son circuit de travail (15), et qui est reliée à celui-ci par au moins une voie de prélèvement (21) et au moins une voie de restitution (22). Suivant l'invention, l'ouverture (25) de la voie de prélèvement (21) dans le circuit de travail (15) est disposée au droit de l'élément moteur (16A), à la périphérie de celui-ci, et il est associé à cette ouverture (25) au moins un déflecteur (26) qui, lié en rotation à l'élément moteur (16A), s'étend dans le circuit de travail (15) à compter d'elle et forme écope. Application, notamment, à l'entraînement progressif de charges importantes susceptibles de surcharges temporaires.
