Abstract
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.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
81 words
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.
Claim 2
Dependent Claim
81 words
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.
Claim 3
Dependent Claim
20 words
A manifold as in claim 1 wherein the isolator is secured to the main body and the flange by molding.
Claim 4
Dependent Claim
30 words
A manifold as in claim 1 wherein the isolator is secured to the flange by molding and the mounting surface of the flange has a sealing bead also molded thereon.
Claim 5
Dependent Claim
32 words
A manifold as in claim 3 wherein the sealing bead is seated in a groove on the flange mounting surface and is formed during the molding of the isolator to the flange.
Claim 6
Dependent Claim
38 words
A manifold as in claim 4 wherein the bead is integrally connected with the isolator through openings in the flange extending between the sealing surface and the groove and filled during the molding of the isolator and bead.
Claim 7
Dependent Claim
19 words
A manifold as in claim 3 wherein the isolator is secured to the main body by an adhesive material.
Claim 8
Dependent Claim
22 words
A manifold as in claim 1 wherein the isolator is secured to the main body and the flange by an adhesive material.
Claim 9
Dependent Claim
141 words
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.
Claim 10
Dependent Claim
141 words
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.
Claim 11
Dependent Claim
52 words
A combination as in claim 8 wherein the manifold main body extends to one side of the engine and has a plenum portion that overhangs one of the cylinder banks, wherein the combination further includes support means including supplemental resilient isolators supporting the plenum portion on said one of the cylinder banks.
Claim 12
Dependent Claim
86 words
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.
Claim 13
Dependent Claim
86 words
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.
