Beschreibung
Zusammenfassung:	The invention related to a piston-pin boss ( 18 ) of a piston ( 6 ) for an internal combustion engine, comprising a piston-pin bore ( 1 ) for receiving a piston pin. To improve the passage of oil and to form an oil reservoir, the interior surface ( 2 ) of the bore comprises a transversal groove ( 5 ) that lies parallel to the longitudinal axis ( 3 ) of the piston-bore ( 1 ) and opens towards the exterior of the piston and an oil circulation groove ( 4 ) that intersects the transversal groove ( 5 ) and encircles the longitudinal axis ( 3 ).
