ABSTRACT:
A gasket with heat-insulating properties is provided for such uses as for mounting a carburetor on an internal-combustion-engine casting. A thick core of heat-insulating resin, such as phenolic resin, is sandwiched between two thin cutout sheets of resilient gasket material. The core provides the heat insulation, and the gasket material provides the resilience needed to assure sealing on rough surfaces. Heat-dissipating fins or the like may also be provided, as well as rings of heat-insulating material which can surround the bolts used to hold the carburetor in place. The core is molded to shape, while the gasket material may be cut out to shape and secured to it by a thermo-setting resin, such as a nitrile-rubber-phenolic-resin material.
