CA 2207433

A piston ring assembly includes a piston (12), and at least one piston ring (20) positioned within a piston groove (18). Stabilization and support of the piston (12) is provided by a support arrangement, including at least one support member (22) positioned radially between a back wall of the ring groove and the piston ring. The support arrangement desirably acts to accommodate transverse loads exerted upon the piston during normal operation, and can optionally be configured for enhanced sealing of gases.

Cet ensemble piston comprend un piston (12) et au moins un segment de piston (20) placé dans une gorge de piston (18). La stabilisation et le support du piston (12) sont dûs à un dispositif de support comprenant au moins un élément de support (22) disposé dans le sens radial entre la paroi arrière de cette gorge de piston et le segment de piston. Ce dispositf de support permet de tenir judicieusement compte des charges transversales affectant le piston pendant son fonctionnement normal, et il peut, à titre facultatif, être configuré de façon à offrir une meilleure étanchéité aux gaz.
