Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on other non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some limited contact-sealing action that creates the seal.

Labyrinth Seal

Labyrinth seals are widely used in turbo machines to reduce leakage flow. The stability of the rotor is influenced by the labyrinth seal as a result of the driving forces generated in the chambers of the seal. A linearized model [1–3] has been widely used to describe the rotordynamic properties of a …

Straight Labyrinth Seal Leakage Calculation — …

Labyrinth seals work by throttling the flow through successive openings in series. In each throttle, static pressure difference accelerares the flow and some of the kinetic eneergy associated with the flow is dissipated by turbulence induced by the intense shear stress and eddy motion in the next chamber.
