ABSTRACT:
Wrist pins for use in pistons are described. The wrist pin comprises an elongate, substantially hollow member having two spaced-apart convex surface portions of substantially cylindrical or oval curvature, the two convex portions being connected by two walls of different curvature. Because the connecting walls are more nearly in compression and bending loads are minimised a lighter wrist pin for a given application may be produced.
