Manifolds for internal combustion engines
US 4301775 A
A manifold for an internal combustion engine comprises a plurality of body parts each formed as an integral casting by pressure casting. A first body part has a mounting flange for the manifold, a plurality of open channels communicating with respective apertures in the mounting flange, and a water chamber communicating with a port in the flange and a further port in the first body part. A second body part overlies the channels so that the first and second body parts define a plurality of gas conduits effecting communication between the apertures and a common orifice. The first and second parts are sealed together along opposed side faces adjacent their outer peripheral edges. The seal along opposing sides allows access to the joints from the exterior of the assembly, permitting connection by electron beam welding or an adhesive, since all the joints are located on the exterior of the assembly a smoother interior surface is preserved and visual inspection of each joint is possible as it is made.
1. A manifold for an internal combustion engine comprising:
a first body part formed as an integral casting having a mounting flange for the manifold;
a plurality of open channels communicating with respective apertures in the mounting flange and a water chamber communicating with a part in the flange and a further port in the first body part;
a second body part formed as an integral casting overlying the channels such that the first and second body parts define a plurality of gas conduits effecting communication between the apertures and a common orifice formed through at least one of the body parts;
a seal formed by the first and second parts being sealed together along opposed side faces adjacent their outer peripheral edges;
the second body part defining an aperture which surrounds said further port in the first body part, a second seal being formed by the second body part being sealed to the first body part along side faces the adjacent edges of the aperture and the further port;
a third body part which coacts with said second body part with said coaction defining a second water chamber effecting communication between the aperture in the second body part and an opening defined in the third body part, the third body part having a side face adjacent its outer peripheral edge which faces a complementary side face of said second body part; the seal is formed by the third said side face of said third body part being sealed to said side surface of said second body part.
2. A manifold for an internal combustion engine comprising:
a plurality of open channels formed in said first body part communicating with respective apertures in the mounting flange and a water chamber communicating with a port in the flange and a further port in the first body part;
said first body part having outer peripheral edges defining the edge of the open channels with a side wall as part thereof;
a second body part formed as an integral casting with a plurality of channels formed therein and positioned to overlie said channels of said first body part such that the channels of the first and second body parts join together to define a plurality of gas conduits effecting communication between the apertures and a common orifice formed through at least one of the body parts;
said second body part having peripheral edges with a side wall facing said side wall of said first body part;
3. A manifold according to claim 2 wherein the seal between the first and second body parts lies in a plane.
6. A manifold according to claim 2 wherein:
said first body part has said side wall inwardly facing said channels of said first body part;
said second body part has an outwardly facing side wall which faces said side wall of said first body part.
7. A manifold as defined in claim 6 wherein:
said first body part has a shoulder inwardly extending toward said channels of said first body part and below said side wall of said first body part to support said peripheral edges of said second body part.
According to the present invention, there is provided a manifold for an internal combustion engine comprising a plurality of body parts each formed as an integral casting, a first body part having a mounting flange for the manifold, a plurality of open channels communicating with respective apertures in the mounting flange and a water chamber communicating with a port in the flange and a further port in the first body part, a second body part overlying the channels so that the first and second body parts define a plurality of gas conduits effecting communicating between the apertures and a common orifice, the first and second parts being sealed together along opposed side faces adjacent their outer peripheral edges.
Referring to the drawings, the intake manifold comprises a first body part 1 formed from pressure cast aluminum. The first body part 1 includes an integral mounting flange 2 which has a flat front face 3 in which are formed four apertures constituting outlets ports 4. The mounting flange 2 also includes five bolt holes 5 by means of which the manifold may be mounted on an internal combustion engine with the outlet ports 4 in registry with the cylinder inlet ports of the engine. Open channels 6 extend rearwardly away from the mounting flange 2 and communicate with a common orifice 7 in the first body part 1 which, in use, is connected to a carburetor. A water chamber 8 is formed integrally with the first body part 1. As best seen in FIG. 2, the water chamber 8 communicates at one end with a port 9 in the mounting flange 2 and at an opposing end with another port 10 which is formed in an upstanding neck 11. A shoulder 14 formed on the inner side face 22 of the body part 1 adjacent the peripheral edge 23.
