Abstract

Foreliggende oppfinnelse angår en portventil 11 som har et ventillegeme 13 med et hulrom 23 og en strømningspassasje 15 som skjærer gjennom hulrommet 23. En setering 21 er montert til legemet 13 ved skjæringen mellom strømningspassasjen 15 og hulrommet, og seteringen 21 har en kontaktflate. En port 17 i hulrommet har også en kontaktflate som på glidende måte samvirker med flaten på seteringen mens den beveges mellom åpen og lukket stilling. Et polymert belegg 29 foreligger på minst en av flatene. Polymeren kan omfatte en mengde karbon-nanorør for avstivning.
