Abstract
A piston ring has a wear-resistant band (38) disposed between two lands (40, 42). The piston ring is split, the division including two oppositely disposed surfaces (52, 70) which are radially and axially inclined and which terminate in one of the lands (40). This construction means that the wear-resistant band (38) terminates at axially extending edges (80, 62) but does not have exposed circumferentially extending edges, which would be prone to damage during manufacture. In one embodiment the band is nearer one edge of the ring than the other and the outer surface of the ring is barrelled assymetrically so that the widest part of the ring is in the centre of the band. <IMAGE>
