RUN OUT TOLERANT RECIPROCATING CYLINDER SLEEVE SEAL CARBON SCRAPER

摘要

A reciprocating cylinder seal assembly (10, 10') has an elastomeric seal, where separate inner (16, 16') and an outer (18, 18') valve seal retainers are located within the reciprocating cylinder seal assembly. The reciprocating cylinder seal assembly (10, 10') better controls radial run out than past seals in reciprocating cylinder engines. Further, the reciprocating cylinder seal assembly may have a scraper (42') that is in contact with the outer valve seal retainer (18').
