ABSTRACT:
An improved staggered seal assembly uses a static element and a rotating element to create a seal. The static element surrounds the rotating element and has at least one fin. The rotating element has at least one long fin and a set of shorter fins. A third component has a staggered fin. The fins create a leakage flow path which throttles the leakage across the seal from a high pressure zone into a low pressure zone.
