Abstract
A low drag fluid seal. The fluid seal includes a lip separated from the rotor shaft, during operation, 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.
