  • Anti-friction sealing rings
    Patent number: 12698829
    Abstract: Systems and methods are provided for a sealing element arranged in a ring groove of a piston assembly to seal against the ring groove at a first interface and to seal against a bore of a cylinder, in which the piston assembly is arranged, at a second interface. A feature of the sealing element is arranged at the first interface for reducing friction between the sealing element and the ring groove. The second interface is without a liquid lubricant or oil during operation.
    Type: Grant

  • Springs for piston ring biasing
    Patent number: 11873906
    Abstract: Systems and methods are provided for a cantilever beam arrangement that preloads ring segments in a multi0segment piston ring arrangement. A piston assembly comprises a piston that comprises a land. A ring segment is arranged against the land. The ring segment comprises a radially inner surface, a radially outer surface for sealing against a bore, and a boss located on the radially inner surface. The piston assembly also includes a beam spring having a proximal end attached to the piston and a distal end in contact with the boss. The beam spring forces at least a portion of the ring segment radially outward by applying a force on the boss.
