Abstract

1. Piston assembly (10), comprising a piston (12) having a cross bore (14) extending therethrough, in which a hollow cylindrical wrist pin (20) is mounted extending through an apertured coupling portion (26) of a connecting rod (24) and having, for its reinforcement, in its bore (22) two press-fitted plugs (42; 44) acting against deformation of said wrist pin (20) and including together with said wrist pin (20) a cavity, whereby a recess (16) extends from the cross bore (14) into said piston (12) for receiving the inner end (28) of said connecting-rod coupling portion (26) and whereby a cut (18) extends from said cross bore (14) to the piston bottom for receiving the outer end (30) of said connecting rod coupling portion (26), characterized by the following features : a) Said plugs (42; 44) are of ceramic material and have apertures (46; 48, 50) for exhausting gasses from the cavity included between said plugs (42; 44) ; b) the axial length of said cut (18) measured in the direction of the cross-bore axis is larger than that of said recess (16) ; c) connecting rod (24) and piston (12) define together two overlap zones (31, 33), each extending outwardly parallel to the cross-bore axis from the outer edge (32, 36) of the inner end (28) of said connecting-rod coupling portion (26) to the wall (34, 38) of said cut (18) ; d) each plug (42; 44) has such an axial length and such an axial position within the wrist-pin bore (22) that it completely spans the corresponding overlap zone (31, 33).
