Abstract

Avsmalnende pluggventil med en fjærinnretning for å tvinge pluggen (4) mot dennes boring(3) i ventillegemet (l)ogjusteringsinnretning(22, 85, 111, 146, 178) for å lokalisere enten pluggen (4) og fjærinnretningen (26, 87, 106, 145, 166) i relative forhåndsbestemte posisjoner. Fjærinnretningen kan omfatte en flat fjær (26, 87) plassert inne i ventillegemet (1), en skivefjær(145) i en boring i drivakslingen (12, 133) eller en bjelke (106, 166) på ventillegemets (1) lokk (9). Justeringsinnretningen kan omfatte en krage (22, 85, 111, 178) eller en skrue (146), som er bevegelig festet til akslingen (12, 133), plugginnretningen (4) eller fjærinnretningen (26, 87, 106, 145, 166).
