Abstract
Ventilsete med ei ytre flate, en bakre ende, en front og en fremre ende. En passasje strekker seg fra den bakre enden til fronten. Et ventilelement er i glidekontakt med fronten. Spenningsavlastningsflenser er anordnet på fronten i områder med høy lagerspenning. Hver flens har en tykkelse som gjør at de kan bøye litt av for å redusere lagerspenning.
