摘要: A seal for sealing the gaps between adjacent turbine blade structures is disclosed in which disposed a compartment formed having first and second surfaces to generally axially extending gap radially gap, respectively. The also has thrust surface obliquely radius from axis of rotation rotor disk are attached engaged with reaction on member located compartment. During disk, centrifugal force acting outward direction transmitted both by contact oblique cause gap.
