Abstract
Cette invention concerne une soupape de surpression destinée à travailler dans une fourchette de pressions de 200 à 600 bars avec une émulsion huile-eau. La surface cylindrique extérieure du clapet présente une profondeur de rugosité d'environ un micron, le joint torique coopérant avec ce clapet présente une dureté finie, son diamètre de section droit étant supérieur au double du diamètre de canaux d'écartement prévus dans le clapet, tandis que le diamètre intérieur de ce joint torique n'est que légèrement plus petit que le diamètre du clapet. Une soupape de ce type est utilisable notamment pour les étançons de mines hydrauliques.
