Abstract

Stor totaktsdieselmotor med minst én sylinder (1), hvor forbrenningskammeret (3) har en avgassåpning (4) som styres av en avgassventil (5) som påvirkes av en aktiveringsinnretning som omfatter et fremarrangement og et returarrangement, idet det på sylinderhodet (2) er montert et ventilhus (9) som har en avgasskanal (8) tilknyttet avgassåpningen (4) fra forbrenningskammeret (3), idet videre en styrehylse (10) for en avgassventilstamme (7) i avgasskanalen (8) er ført gjennom den øvre veggen i avgasskanalen (8), hvilket returarrangement omfatter et stempel (15) på ventilstammen (7) og et driftskammer (17) som begrenses av dette stempelet (15) og kan lades med trykkluft, hvilket driftskammer (17) er avtettet mot et ringgap (11) hvortil olje kan tilføres og som ligger mellom styreflatene på styrehylsen (10) og ventilstammen (7) og har forbindelse med avgasskanalen (8), hvilken avtetning innbefatter en tetningsanordning som er anordnet i området til den øvre, fra avgasskanalen vendte ende av ringgapet (11) og innbefatter minst én pakningsring (22). En enkel konstruksjon og en vedlikeholdsfri drift kan oppnås ved at det over pakningsringen (22) i tetningsinnretningen er anordnet et oljereservoar (24 eller 32 eller 36) som kan tilføres olje, hvilken olje vil forefinnes på den øvre siden av pakningsringen (22), dvs. den siden som vender fra avgasskanalen (8).
