APPARATUS AND METHOD FOR SEALING INTERNAL COMBUSTION ENGINES |
摘要 |
An improved sealing means for internal combustion engines comprising a combination of a metal primary sealing ring positioned substantially within a groove on the piston, and a compliant secondary sealing ring positioned in the groove behind the primary compression ring so that the compressed combustion gases force the compliant secondary sealing ring to form a seal between the groove and the primary sealing ring. In the preferred embodiment, the gapped ring is non-planar in order to provide effective sealing in a ported fixed-piston, rotating and translating cylinder engine such as the Deckard engine. Alternate embodiments include gapless rings with only a primary compression ring, and gapless rings with a compliant secondary sealing ring. An alternate embodiment is a single piece metal-capped compliant secondary sealing ring.
