Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
An intercooler on an internal combustion engine comprising, an internal combustion engine, an intercooler including a housing defining an inlet passage and an inlet plenum chamber, said housing defining an air supply chamber adapted for supplying air to the combustion chambers of the internal combustion engine, an intercooler core chamber intermediate said plenum chamber and said air supply chamber, an intercooler core in said intercooler core chamber, a source of coolant on said engine connected to said intercooler core, deflector means extending from said inlet passage into said plenum chamber including at least two deflectors extending downwardly and outwardly from said inlet passage toward the housing walls and an air flow divider intermediate the deflectors downstream of the inlet passage for guiding incoming air from said inlet passage for uniform distribution of air to all portions of the intercooler cooling surfaces and uniform cooling of air flow through the intercooler.
Claim 2
Dependent Claim
150 words
An intercooler on an internal combustion engine comprising, an internal combustion engine, an intercooler including a housing defining an inlet passage and an inlet plenum chamber, said housing defining an air supply chamber adapted for supplying air to the combustion chambers of the internal combustion engine, an intercooler core chamber intermediate said plenum chamber and said air supply chamber, an intercooler core in said intercooler core chamber, a source of coolant on said engine connected to said intercooler core, deflector means extending from said inlet passage into said plenum chamber including at least two deflectors extending downwardly and outwardly from said inlet passage toward the housing walls and an air flow divider intermediate the deflectors downstream of the inlet passage for guiding incoming air from said inlet passage for uniform distribution of air to all portions of the intercooler cooling surfaces and uniform cooling of air flow through the intercooler.
Claim 3
Dependent Claim
31 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said deflector means defines essentially a plurality of passages from said inlet passage to said intercooler core.
Claim 4
Dependent Claim
35 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said deflector means includes two air deflectors laterally of said divider for providing even distribution of air over said intercooler core.
Claim 5
Dependent Claim
39 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said housing means defines plural outlet passages from said air supply chamber adapted for connection to a plurality of cylinders in said internal combustion engine.
Claim 6
Dependent Claim
29 words
An intercooler on an internal combustion engine as set forth in claim 1 including, means defining a central positioning of said inlet passage in connection with said plenum chamber.
Claim 7
Dependent Claim
39 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said deflector means define partitions extending from said inlet passage into said plenum chamber for controlling the distribution of air flow across said intercooler core.
Claim 8
Dependent Claim
77 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said deflector means essentially defines a plurality of air passages extending from said inlet passage to said intercooler core with cross-sectional areas of the passages at the inlet passage being proportional to the cross-sectional areas near the intercooler core for distributing incoming air across the cooling surface of said intercooler core for a uniform flow rate through all portions of said intercooler core.
Claim 9
Dependent Claim
38 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein the housing of said plenum chamber and said deflector means define at least four passage means from said inlet passage to said intercooler core.
Claim 10
Dependent Claim
28 words
An intercooler on an internal combustion engine as set forth in claim 1, wherein said housing of said plenum chamber forms an integral structure with said deflector means.
