Abstract
A device for pivotal connection of piston ( ) and connecting rod ( ) in a reciprocating-piston engine comprises a connecting member ( ) integral with the piston, with a bearing surface ( ) for a connecting-rod eye ( ), which together with the bearing surface ( ) forms the pivot bearing of the connecting rod ( ) on the piston side; the connecting member ( ) is provided at least in the region of the bolting with planar contact faces ( ), which together with mating faces ( ) on the inside of the piston form a common dividing plane ( ); the connecting member ( ) is fixed on the side of the piston ( ) facing away from the combustion chamber by means of one or more connecting bolts ( ) passed through bores in the piston head ( ); the bearing surface ( ) is much broader toward the straight portion ( ) of the connecting rod than on its side facing the piston ( ).
