摘要： A compression piston ring includes a ring gap defined by facing first and second end faces; a ring back situated diametrically opposite the ring gap; first and fourth quadrants extending from opposite sides of the ring gap and second and third quadrants extending from opposite sides of the ring back to the respective first and fourth quadrants. The first end face is situated in the first quadrant and the second end face is situated in the fourth quadrant. The wall thickness of the compression piston ring is reduced exclusively in the first and fourth quadrants.

摘要： The invention relates to a piston ring comprising a slit forming a joint, a bearing surface, an inner peripheral surface, and upper and lower flanks extending thereinbetween. An inconstant cross-sectional interruption is provided in the region of the inner peripheral surface and, seen from the peripheral direction, is larger in the region of the joint than in the region which diametrically opposes the joint. The wall thickness of the inventive piston ring varies in the peripheral direction and is smaller in the region of the joint than in the region which diametrically opposes the joint. The relation between the wall thickness and the cross-sectional interruption is always such that the piston ring has a constant torsional angle, seen over the periphery.

摘要： A piston ring exhibiting particles capable of wear resistance on its shoulder is produced by producing a melt of the base materials of a metal material, adding ceramic particles to the melt, pouring the melt into a prefabricated mold and cooling the melt. During cooling, the mold is aligned such that the ceramic particles gather on at least one of the piston ring shoulders.

摘要翻译： 本发明涉及一种活塞环，其包括形成接头的狭缝，支承表面，内周表面以及在其之间延伸的上下侧面。 在内周面的区域设有不规则的截面中断，从沿周向方向看，在接头的区域比在与接头直径相对的区域大。 本发明的活塞环的壁厚在圆周方向上变化，并且在接头的区域中比在与接头直径相对的区域中更小。 壁厚和截面中断之间的关系总是使得活塞环在周边看到一个恒定的扭转角。
