Trang 1Contact pressure: At a seal interface a part of the force needed for equilibrium is supplied by
fluid pressure and a part by contact pressure
Elastomer(ic): A material having the property of recovery of shape after deformation; rubberlike
materials
Ferrofluid: A liquid containing a suspension of magnetic particles.
Preload: The clamping load before pressure is applied.
Sealing clearance: The effective gap between two surfaces.
Self-energized: The preload is supplied by the elastic behavior of the material itself.
