ABSTRACT:
A cylinder gasket having three flat metal foils connected together. The fluid passages between the cylinder head and engine block are sealed by forming a centrally located first aperture in the two external flat metal foils. A smaller second aperture, centrally located to the first aperture, is formed in the central flat metal foil so as to form first and second flat zones. In the preferred embodiment, an elastomer band is attached to the central flat metal foil around the periphery of the second aperture and the first and second flat zones to seal the fluid passages. The cylinder lining is sealed by a second ring member with an external round lip. The second ring member is mounted in a third aperture in the two external flat metal foils centrally located with the cylinder lining. The external round lip is sandwiched between the two external flat metal foils and a fourth aperture in the central flat metal foil which is centrally located with the third aperture. An escape channel is provided to vent gases to the exterior of the engine. In an alternate embodiment, a C shaped circular member is attached to the central flat metal foil around the periphery of the second aperture. A metal ring is interposed the C shaped circular member and first ring member.
