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.
Claims16
An engine inlet manifold having a main body, a mounting flange and a resilient isolator adherently secured to spaced opposed surfaces of the body and the flange and defining therewith a fluid passage sealed by the isolator at the joint between the surfaces, the flange including means for securing the flange solidly to a ported engine component and the isolator being operative to allow limited relative motion between the flange and the main body while supporting the body on the flange.
In combination in a V-type engine having a pair of angularly disposed cylinder banks extending from a common crankcase and defining an intermediate valley,
- an engine inlet manifold secured to and connecting with both said cylinder banks to carry charging air from a common supply to cylinders in said cylinder banks, said manifold having a main body, a pair of mounting flanges and a pair of resilient isolators, one adherently secured to spaced opposed surfaces of each flange and the body and defining therewith a fluid passage sealed by the isolator at the joints between the surfaces, each flange including means for securing the flange solidly to a respective one of the cylinder banks and the isolators being operative to allow limited relative motion between the cylinder banks and the manifold main body while supporting the main body on the engine.
An engine inlet manifold component having a body, a pair of mounting flanges and a pair of resilient isolators, one adherently secured to spaced opposed surfaces of each flange and the body and defining therewith a fluid passage sealed by the isolator at the joints between the surfaces, each flange including means for securing the flange solidly to a respective ported engine component, and the isolators being operative to allow limited relative motion between the flanges and the body while supporting the body on the flanges.
