Internal combustion engine piston cooling channel stands at angle to gudgeon pin axis as also third piston axis in the piston head with relieving hole at channel point furthest from piston head.

摘要

The cooling channel (9) is arranged in the piston head (2) at an angle both to the gudgeon pin axis (6) and to third axis of the piston. The piston has a relieving hole for medium bleed at the point in the channel furthest from the piston head. The channel lies in the bottom half of the region between piston head (2) and the upper apex part of the gudgeon on bearing facing the piston head.
