DK 181012 B1 9 Patentkrav
1. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor omfattende en smøreforsyning (2) af smørevæske og mindst én plejlstang (3) — omfattende en første ende (4) med et første leje (5) konfigureret til at være forbundet til et krydshoved (6), en anden ende (7) med et andet leje (8) konfigureret til at blive forbundet med en krumtapaksel (9), og en stangdel (10) mellem den første ende (4) og anden ende (7), hvor plejlstangen (3) har en aksial udstrækning med en aksial centerlinje (L), hvor plejlstangen (3) — yderligere omfatter en smørevæskekanal (11), der er konfigureret til at tilføre smørevæske fra det første leje (5) ) til det andet leje (8), og mindst et stivnedsmodificerende hul (12) anbragt i plejlstangen (3), kendetegnet ved, at plejlstangen (3) er pladeformet og smørevæskekanalen (11) er ikke-centreret i forhold til den aksiale midterlinje (L) og ikke interfererer med det eller de — stivhedsmodificerende huller (12).
2. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge krav 1, kendetegnet ved, at smørevæskekanalen (11) strækker sig fra det første leje (5) til det andet leje (8) i en retning, der er skråtstillet i forhold til den — aksiale midterlinje (L) af plejlstangen (3).
3. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge krav 1, kendetegnet ved, at smørevæskekanalen (11) strækker sig fra det første leje (5) til det andet leje (8) i en retning, der er væsentlig parallel i forhold til den aksiale midterlinje (L) af plejlstangen (3).
4. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge krav 1, kendetegnet ved, at smørevæskekanalen (11) strækker sig fra det første leje (5) til det andet leje (8) følgende over en første del en første retning, der er skråtstillet med en første vinkel i forhold til nævnte aksiale midterlinje (L) af plejlstangen (3) og følgende over en anden del en anden retning, der er skråtstillet med en anden vinkel i forhold til nævnte aksiale midterlinje (L) af plejlstangen ( 3).
DK 181012 B1 10

Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at det stivnedsmodificerende hul (12) er cirkulært, ovalt, polygonalt eller fortrinsvis tøndeformet, dvs. rektangulært i sin basisform med udadbuede sideflader.
6. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at forholdet mellem bredden af det stivhedsmodificerende hul (12) og diameteren af krumtapakslen (9) er inden for området fra 1/10 til 3/10, fortrinsvis ca. 2/10.
7. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at forholdet mellem afstanden mellem det stivhedsmodificerende hul (12) og diameteren af krumtapakslen (9) er inden for området fra 1/10 til 4/10, fortrinsvis mellem 3/20 og 3/10 og mest fortrinsvis ca. 2/10.
8. Stor to-takts uniflow skyllet turboladet krydshovedforbrændingsmotor ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at det mindst ene stivhedsmodificerende hul (12) er arrangeret symmetrisk omkring den — aksiale midterlinje (L) af plejlstangen (3).
