Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
54 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet portion which penetrates into the intake manifold and communicates to an exhaust manifold, the inlet portion being made of a foaming member; and at least one hole formed in a portion of the inlet portion inside the intake manifold.
Claim 2
Dependent Claim
54 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet portion which penetrates into the intake manifold and communicates to an exhaust manifold, the inlet portion being made of a foaming member; and at least one hole formed in a portion of the inlet portion inside the intake manifold.
Claim 3
Dependent Claim
67 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet pipe shaped portion which penetrates into the intake manifold and communicates to an exhaust manifold; and a porous member located on the inlet pipe shaped portion inside the intake manifold and extending from an inner surface of the intake manifold, the porous member mixing the exhausted gas and an intake air therein.
Claim 4
Dependent Claim
67 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet pipe shaped portion which penetrates into the intake manifold and communicates to an exhaust manifold; and a porous member located on the inlet pipe shaped portion inside the intake manifold and extending from an inner surface of the intake manifold, the porous member mixing the exhausted gas and an intake air therein.
Claim 5
Dependent Claim
43 words

Claim 6
Dependent Claim
79 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet portion which penetrates into the intake manifold and communicates to an exhaust manifold, the inlet portion including a flange which is surrounding the inlet portion, and the inlet portion and the flange being formed as a single body, and the flange being connected to the intake manifold; and at least one hole formed in a portion of the inlet portion inside the intake manifold.
Claim 7
Dependent Claim
79 words
An exhausted gas recycle device which is installed in an intake manifold, comprising: an inlet portion which penetrates into the intake manifold and communicates to an exhaust manifold, the inlet portion including a flange which is surrounding the inlet portion, and the inlet portion and the flange being formed as a single body, and the flange being connected to the intake manifold; and at least one hole formed in a portion of the inlet portion inside the intake manifold.
Claim 8
Dependent Claim
