IMPROVED RADIAL COVERAGE PISTON RING GROOVE ARRANGEMENT
A main shaft bearing compartment seal system is described herein. A modified ring groove geometry creates two distinct cavities or steps (215, 218) for a piston ring (230) and a wave spring (240). This concept provides a separate groove cavity for the spring (240) independent of the fool-proofing an...

| description | A main shaft bearing compartment seal system is described herein. A modified ring groove geometry creates two distinct cavities or steps (215, 218) for a piston ring (230) and a wave spring (240). This concept provides a separate groove cavity for the spring (240) independent of the fool-proofing and clearance cavity. This modified ring groove geometry increases first face coverage and reduces exposure risk for eccentricity of wave spring (240) to piston ring (230), to avoid potential disengagement and improve function and performance of the seal assembly and an engine (20). |
