ATTACHMENT FOR EXHAUST PIPE
This invention relates to an exhaust pipe for an internal combustion engine and more particularly to à
means of attaching the exhaust pipe to the outlet of a supercharger and providing a means of supporting a mufler. The exhaust pipe can be rotated to provide infinite positioning of the exhaust pipe.
Conventional exhaust pipes of cast iron have a machined surface to assure seal integrity in mounting with a mating sur~ace to form an exhaust pipe coupling.
If a steel flange is used on the exhaust pipe or elbow, the flange must be welded on the pipe to provide the flange for sealing. If orientation of the exhaust pipe is changed, a cast iron pipe must be drilled differently or a flange of a welded exhaust pipe must have a different flange welded to the pipe to accommodate any change in positioning of the exhaust pipe.
The applicant's invention has a rolled bead on the outer periphery of the exhaust pipe to form a seal and allow an infinite number of positions of the exhaust pipe by the use of two components.
U.S. patent 3,035,505, Lee, and U.S. 3,133,612, Sailler, show exhaust pipes. The Lee patent shows a means of trapping moisture and drainin~ the moisture before it is allowed to enter the internal combustion engine while the Sailler patent shows a laminated engine exhaust pipe for sound deadening of the exhaust system.
The applicant's invention provides a coupling for mounting of the exhaust pipe and a seal in the coupling permitting infinite positioning of the exhaust pipe~
It is an object of this invention to provide a mounting for an exhaust pipe of an internal combustion engine.
It is another object of this invention to provide a coupling for mounting of the exhaust pipe and to provide seal integrity of the exhaust pipe coupling.
It is a further object of this invention to provide a coupling for mounting an exhaust pipe and provide seal integrity between the supercharger discharge pipe and the exhaust pipe and for supporting of a muffler. The coupling provides for infinite positioning of the exhaust pipe.
Summary of the Invention The objectives of this invention are met by an exhaust system for an internal combustion engine which includes a supporting exhaust conduit member including a peripheral flange defining a relatively sharp edge of approximately 90 degrees, an exhaust pipe of resilient material including an inlet portion received in the conduit member and including a deformable peripheral bead which is hollow and of greater diameter than the inlet portion, an aligning external peripheral surEace on the inlet portion of the exhaust pipe bearing against the inner peripheral surface of the conduit member, a clamping ring encompassing the exhaust pipe and axially engaging the peripheral bead, and releasable fastening means clamping the opposing axial sides of the peripheral bead and pressing the edge of the flange firmly against the bead to effect a seal at the edge between the support member and the exhaust pipe by embedding the edge into said bead.
Referring to the drawings, a preferred embodiment of this invention is illustrated.
Fig. 1 illustrates a side elevation view of a turbo-charger and the exhaust pipe mounting.
Fig. 2 is an end view of the turbo-charger showing the exhaust pipe mounting and a support for a muffler.
Fig. 3 is a cross section view of the turbo-charger supporting flange, the exhaust pipe and a clamping ring forming a coupling.
Referring to the drawings, the turbo-charger 1 is mounted on an engine 2. Exhaust gas is supplied through the conduit 3 to the turbine 4 which drives the compressor 5 compressing air in the conduit 60 which D
- 2a -leads to the intake manifold. The turbine 4 allows exhaust gas to expand and then delivers exhaust gas to the discharge conduit 6. Discharge conduit 6 is connected to the exhaust pipe 7 which supports a muffler 8 for the engine. The turbo-charger discharge conduit 6 is integral with the flange 9 which embraces the exhaust pipe inlet 10 of the exhaust pipe 7. The bead 11 is a rolled bead rolled from the inside forming a raised ridge around the periphery of the exhaust pipe. A portion 12 of the exhaust pipe 7 extends to the elbow 13. This clamping ring 14 is fastened by a plurality of bolts 15 and nuts 16 which clamp the flange 9 and clamping ring 14 firmly against the bead 11 to form seal integrity between ~1~52S2 the discharge conduit 6 of the turbo charger l and the exhaust pipe 7. The exhaust pipe can be rotated to any position desired by merely loosening the bolts and nuts on the clamping ring 14 and rotating the exhaust pipe.
By tightening of the bolts, a positive seal in the re-oriented position is achieved. Since the bolts 15 do not extend through a flange integral with the exhaust pipe, but merely extend through a clamping ring, infinite positioning of the exhaust pipe is possible.
The device operates in the following described manner. The exhaust pipe 7 is positioned in the turbo-charger discharge conduit 6 and assembled with the bead 11 contacting the flange 9 of the turbo-charger dischar:ge conduit. The clamping ring 14 is positioned over the exhaust pipe and similarly abuts against the outer surface of the bead 11. Bolting of the clamp ring 14 to the flange 9 assures a fixed position of the exhaust pipe 7 and seal integrity because of the firm contact between the flange 9 and the bead 11. Repositioning of the exhaust pipe by rotation of the pipe is easily accomplished by loosening the bolts 15 and rotating the exhaust pipe to the desired orientation. The mounting of an exhaust pipe in this manner eliminates any need for welding a flange to the exhaust pipe of a steel pipe for mounting of the pipe and permits the versatility of orientation of the pipe as desired. In contrast, the conventional cast iron exhaust requires drilling of holes to accommodate the bolts 15, and limits the positioning of the exhaust pipe. With the applicant's invention, the exhaust pipe is capable of infinite positionin3 to accommodate orientation of the pipe and the muffler on the engine.
