Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A gas exhaust device for and in combination with a combustion engine and a structure on which structure the engine is elastically mounted, said device comprising an exhaust manifold carried by the engine, an exhaust pipe which includes a flexible section and is connected to the manifold, the flexible section being disposed adjacent an upstream end of the exhaust pipe relative to the flow of exhaust gases through the pipe, a support independent of said structure, a part of the exhaust pipe located immediately downstream of the flexible section relative to said flow being connected to the support, and a flexible connection connecting the support to the engine.
Claim 2
Dependent Claim
108 words
A gas exhaust device for and in combination with a combustion engine and a structure on which structure the engine is elastically mounted, said device comprising an exhaust manifold carried by the engine, an exhaust pipe which includes a flexible section and is connected to the manifold, the flexible section being disposed adjacent an upstream end of the exhaust pipe relative to the flow of exhaust gases through the pipe, a support independent of said structure, a part of the exhaust pipe located immediately downstream of the flexible section relative to said flow being connected to the support, and a flexible connection connecting the support to the engine.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1, wherein said part of the exhaust pipe immediately downstream of the flexible section is connected rigidly to the support which support extends in a direction substantially parallel to the flexible section.
Claim 4
Dependent Claim
32 words
A device as claimed in claim 1, wherein the support comprises an arm and a collar fixing the arm to said part of the exhaust pipe immediately downstream of the flexible section.
Claim 5
Dependent Claim
42 words
A device as claimed in claim 1, wherein the flexible connection comprises two armatures, a sleeve of elastomer bonded between the armatures, one of which armatures is connected to the support and the other of which armatures is connected to the engine.
Claim 6
Dependent Claim
17 words
A device as claimed in claim 1, wherein the flexible section is corrugated pipe constituting a structure.
