Abstract
A moisture trap is formed as an integral part of the wall of an exhaust conduit. Tapered surfaces can be provided to direct condensate downwardly and into a reservoir of the moisture trap where the moisture is retained until the temperature of the exhaust system reaches adequate magnitudes to evaporate the water and conduct it out of the exhaust system along with the exhaust gases.
Claims5
An exhaust system, comprising:
- an exhaust conduit connectable in fluid communication with an engine, said exhaust conduit having a central axis;
- a wall of said exhaust conduit having an internal surface which is shaped to direct exhaust gases away from said engine;
- and
- a reservoir formed as an integral portion of said exhaust conduit, said reservoir being shaped to receive water which flows under the effect of gravity on said internal surface, said reservoir having an inner wall surface and an outer wall surface, said inner wall surface of said reservoir being displaced radially outward from said internal surface of said exhaust conduit, said internal surface of said exhaust conduit being tapered to extend downward and radially outward from said central axis to form a surface that extends from said internal surface to said outer wall surface, said reservoir being formed in a thickness of said wall of said exhaust conduit.
