| 摘要 |
The invention concerns a hydrokinetic apparatus comprising a housing (11) including, rotationally symmetrical about an axis, a casing (15-18) provided with a transverse wall (16) capable of being linked in rotation to an input shaft and a blade wheel or impeller (20) capable of driving in hydrokinetic transmission a bladed turbine wheel (28), the impeller (20) and the turbine wheel (28) consisting of shells (18-25) with blades (21-29) integral with the inner surface (19-56) of the shells (18-55), wherein a central core is designed to guide the fluid: the shell (55) of the turbine (28) is deformed by a hollow subsidence (57) and the core (60) bears a bossing (67) matching the subsidence (57) in shape extending along the latter maintaining the passage cross-section constant whatever the diameter. |
