  • Patent number: 4901681
    Abstract: An intake manifold assembly for a V-type engine utilizes separate flange members that are resiliently connected to a manifold body through adherently secured resilient vibration absorbing isolators. The flanges and isolators combine with the body to define sealed resilient fluid conducting joints that provide the sole support for and resiliently isolate at least the adjacent portions of the manifold body. They also provide for connection of the manifold to the engine using conventional non-isolating connecting bolts or fastening means which are easily applied and removed and limit the number of special separate parts required at assembly.
