Title (EN) AN ANNULAR RING GROOVE OF A PISTON
(FR) RAINURE D'ANNEAU CIRCULAIRE D'UN PISTON
Abstract:
(EN) A power cylinder system (8) for a reciprocating engine (10) includes a piston (20) configured to move within a cylinder (26) of the reciprocating engine. The system also includes a groove (50) extending circumferentially about the piston and configured to support a ring (42). An axially-facing surface of the groove has circumferential undulations at ambient temperatures that are configured to compensate for distortions to the groove caused by operation of the reciprocating engine.
(FR) L'invention concerne un système de vérin d'assistance (8) pour un moteur à mouvement alternatif (10) comprenant un piston (20) configuré pour se déplacer à l'intérieur d'un cylindre (26) du moteur à mouvement alternatif. Le système comprend également une rainure (50) qui s'étend de manière circonférentielle autour du piston et configurée pour supporter un anneau (42). Une surface de la rainure orientée dans le sens axial présente des ondulations circonférentielles aux températures ambiantes, lesquelles sont configurées pour compenser les déformations de la rainure provoquées par le fonctionnement du moteur à mouvement alternatif.
