Abstract
A hydrokinetic coupling device is intended, in particular, for a motor vehicle. The hydrokinetic coupling device comprises a casing rotationally connecting a driving shaft and an impeller wheel, a turbine wheel fixed to a turbine hub rotationally connected to a driven shaft, a clutch locking the coupling of the driving and driven shafts, and a damping element comprising elastic washers for restricting the essentially-radial circulation of the fluid at least inside a front axial space which is located between a front guide washer and a web, such that the fluid circulates though the lockup clutch of the device.
