Abstract
A hydrodynamic power transmission unit is constructed with cylindrical bearings positioned in the annular space between the outer hollow driver shaft and the concentrically disposed inner driven shaft and flow channels are provided to not only supply lubricating oil to the cylindrical bearings independently of the drive fluid supplied to the impeller and turbine discs but also to remove the spent lubricating oil in a way that it does not mix with the drive fluid. The resultant transmission unit, which can be used as a clutch for driving the cooling fan of an internal combustion engine, is more reliable and less expensive than prior art transmission units, and less noisy.
