Abstract

Abstract A universal exhaust gas manifold comprises as a first part a ''''standardized'''' elongated exhaust gas receiver having a single longitudinally extending unobstructed entry port and as a second part a variably designed gas duct assembly whose only prescribed design parameter is that the bounding dimensions of its group of gas riser ports must fall within the outline of the receiver''s entry port.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 206 words
A universal exhaust gas manifold assembly comprising: A. an exhaust duct assembly comprising, 1. a face plate having a joining surface, 2. a plurality of gas ducts on the side opposite said face plate joining surface and 3. means forming openings in said face plate from said gas ducts, and B. an elongated cast metal gas receiver having 1. an internal cavity extending lengthwise thereof for receiving exhaust gases, 2. a joining surface extending along the side of said receiver and conforming to said face plate joining surface i. said surface having means forming at least one longitudinal opening therein which is in communication with said cavity, and ii. which is aligned to receive gas from two or more of said gas ducts, whereby said gas receiver may be connected to any one of a number of face plates having varying gas duct locations along the face plate for different internal combustion engine configurations; and 3. means forming a cooling jacket cast around said gas receiver internal cavity, said cooling jacket having a plurality of openings on said gas receiver joining surface through which cooling fluid is brought in contact with said face plate joining surface when said face plate is joined to said gas receiver.
Claim 2
Dependent Claim 206 words
A universal exhaust gas manifold assembly comprising: A. an exhaust duct assembly comprising, 1. a face plate having a joining surface, 2. a plurality of gas ducts on the side opposite said face plate joining surface and 3. means forming openings in said face plate from said gas ducts, and B. an elongated cast metal gas receiver having 1. an internal cavity extending lengthwise thereof for receiving exhaust gases, 2. a joining surface extending along the side of said receiver and conforming to said face plate joining surface i. said surface having means forming at least one longitudinal opening therein which is in communication with said cavity, and ii. which is aligned to receive gas from two or more of said gas ducts, whereby said gas receiver may be connected to any one of a number of face plates having varying gas duct locations along the face plate for different internal combustion engine configurations; and 3. means forming a cooling jacket cast around said gas receiver internal cavity, said cooling jacket having a plurality of openings on said gas receiver joining surface through which cooling fluid is brought in contact with said face plate joining surface when said face plate is joined to said gas receiver.
Claim 3
Dependent Claim 15 words
a plurality of gas ducts on the side opposite said face plate joining surface and
Claim 4
Dependent Claim 15 words
a plurality of gas ducts on the side opposite said face plate joining surface and
Claim 5
Dependent Claim 85 words
a joining surface extending along the side of said receiver and conforming to said face plate joining surface i. said surface having means forming at least one longitudinal opening therein which is in communication with said cavity, and ii. which is aligned to receive gas from two or more of said gas ducts, whereby said gas receiver may be connected to any one of a number of face plates having varying gas duct locations along the face plate for different internal combustion engine configurations; and
Claim 6
Dependent Claim 85 words
a joining surface extending along the side of said receiver and conforming to said face plate joining surface i. said surface having means forming at least one longitudinal opening therein which is in communication with said cavity, and ii. which is aligned to receive gas from two or more of said gas ducts, whereby said gas receiver may be connected to any one of a number of face plates having varying gas duct locations along the face plate for different internal combustion engine configurations; and
Claim 7
Dependent Claim 50 words
means forming a cooling jacket cast around said gas receiver internal cavity, said cooling jacket having a plurality of openings on said gas receiver joining surface through which cooling fluid is brought in contact with said face plate joining surface when said face plate is joined to said gas receiver.
Claim 8
Dependent Claim 50 words
means forming a cooling jacket cast around said gas receiver internal cavity, said cooling jacket having a plurality of openings on said gas receiver joining surface through which cooling fluid is brought in contact with said face plate joining surface when said face plate is joined to said gas receiver.
Claim 9
Dependent Claim 20 words
means forming openings in said face plate from said gas ducts, and B. an elongated cast metal gas receiver having
Claim 10
Dependent Claim 20 words
means forming openings in said face plate from said gas ducts, and B. an elongated cast metal gas receiver having
