Abstract

An aspirating face seal assembly includes a stationary component and a seal body defining a seal face. The seal body defines a fluid feed passage within the seal body. The fluid feed passage includes an inlet, and one or more feed ports defined along the seal face. The seal body is moveably coupled to the stationary component via a resilient member. A first-pressure plenum is defined radially outward from the seal body and a second-pressure plenum is defined radially inward from the seal body. The seal assembly further includes a plenum seal forming a seal between a portion of the seal body and the stationary component and at least partially defining a third-pressure plenum in fluid communication with a high-pressure fluid source and with the inlet of the fluid feed passage. The third-pressure plenum is pressurized at a higher pressure than both the first-pressure plenum and the second-pressure plenum.
