Patent abstract
A low drag fluid seal. The fluid seal includes a rigid lip separated from the rotor shaft by a gap, the gap being sufficient narrow, radially, to prevent liquid from seeping through the gap at an unacceptable rate, but sufficiently wide, radially, to avoid unacceptably high viscous drag. Fluid that seeps through the gap accumulates in a recovery cavity and is recovered by a scavenge pump.
