Abstract:
1. A crankshaft including: a journal; a first crankpin; a second crankpin; a first arm connecting the first crankpin to the journal; a second arm connecting the second crankpin to the journal; a first straight conduit extending from the first crankpin to the journal, emerging at a surface of the first crankpin at its median transverse plane and passing roughly to the center of the median plane of the first arm; a second straight conduit extending from the second crankpin to the journal, emerging at a surface of the second crankpin at its median transverse plane and passing roughly to the center of the median plane of the second arm, wherein the crankshaft exhibits a geometry such that it cannot additionally include a diametric conduit in the median transverse plane of the journal fluidly joining the first conduit and second conduit; and a third straight conduit, non-diametric, disposed in the median transverse plane of the journal, fluidly connecting the first conduit and the second conduit.
