Abstract
Skovlbladdemper for en turbomaskin har et demperlegeme med første og andre dempningsflate for inngrep med henholdsvis en første og en andre dempningsflate på innbyrdes nærliggende første og andre skovlblad. Demperen har en tetning med et første parti i inngrep med dempelegemet for å motstå relativ bevegelse av tetningen i minst én retning og et andre parti i inngrep med minst ett av skovlbladene og som fordelaktig danner en tetning for å motvirke oppstrøms gassinntrengning.
