Abstract: A thrust washer for a flange half-bearing may include a semi-annular panel having an inner edge and an outer edge. A plurality of hooking lugs may project inwardly from the inner edge of the panel. The hooking lugs may have at least one latching edge configured to engage with a corresponding opening in a bearing shell received by the thrust washer and prevent disconnection of the thrust washer and the bearing shell without deformation of the bearing shell. The hooking lugs may have a hooking lug inner portion proximate to a central part of the thrust washer around the inner edge of the panel for engaging against an edge of the corresponding opening of the bearing shell, and a hooking lug outer portion remote from the central part around the inner edge of the panel. The hooking lug inner portion may be thinner than the hooking lug outer portion.

Abstract: A piston ring for the piston of an internal combustion engine, comprising, on a lower side of the piston ring, a circular, radially inner bezel, the width thereof reducing, on both sides of the ring stop, up to the side of the piston ring that is opposite the ring stop, in a symmetrical manner in relation to a radially situated axis and runs through the ring stop, and the bezel on the lower side of the piston ring is arranged away from the piston base. A good oil-scraping effect of the piston ring is obtained over the entire periphery of the inner wall of the cylinder.

Abstract: The invention relates to a piston ring (1) for the piston of an internal combustion engine, comprising a circular, radially inner bezel (2), the width thereof reducing, on both sides of the ring stop (3), up to the side (4) of the piston ring (1) that is opposite the ring stop (3), in a symmetrical manner in relation to a radially situated axis (8) and runs through the ring stop (3), and the bezel on the lower side of the piston ring (1) is arranged away from the piston base. A good oil-scraping effect of the piston ring (1) is obtained over the entire periphery of the inner wall of the cylinder.
