Abstract

A fuel equalization system includes a filter box for accepting an air stream and a fuel stream, the air stream and the fuel stream mixing to form a mixed air/fuel stream. A blower is provided that has an inlet for accepting the mixed air/fuel stream from the filter box. An air deflection member is positioned in the path of the mixed air/fuel stream, between the filter box and the inlet, so as to reduce the turbulence of the mixed air/fuel stream.

Claims (33)

1. A fuel equalization system, comprising:

a filter box for accepting an air stream and a fuel stream, said air stream and said fuel stream mixing to form a mixed air/fuel stream;

a blower;

a vaned impeller in fluid communication with said blower and having an inlet for accepting said mixed air/fuel stream from said filter box prior to said mixed air/fuel stream being presented to said blower; and

a substantially planar baffle disposed across the inlet of said impeller in the path of said mixed air/fuel stream, said baffle being fixed in position and extending through said inlet and into said impeller, wherein said baffle permits an unobstructed and simultaneous flow of said mixed air/fuel stream on opposing sides of said baffle; and

wherein vanes of said vaned impeller and said baffle are configured to reduce the velocity and rotation of any redirected air/fuel stream passing therethrough.

2. The fuel equalization system of claim 1 , wherein:

said baffle substantially bisects said impeller.

3. The system according to claim 1 , wherein said impeller is movable together with said blower.

4. The system according to claim 1 , wherein said impeller is fixedly connected to said duct section.

5. A method of reducing turbulence within a mixed air/fuel stream being provided to a blower, said method comprising:

arranging a filter box to be in fluid communication with said blower;

providing said filter box with said mixed air/fuel stream;

channeling said mixed air/fuel stream along a path from said filter box to said blower;

arranging an inlet opening in said blower to accept said mixed air/fuel stream;

forming a duct between said filter box and said inlet so as to define said path;

positioning a vaned impeller in a portion of said duct such that air returned from said blower through said inlet opening passes between the vanes of said impeller;

fixedly positioning a substantially planar baffle within said duct so as to retard the velocity and swirling nature of said mixed air/fuel stream; and

extending said baffle into said portion of said duct and said impellers;

wherein said vanes and said baffle reduce the velocity and rotation of said returned air in said duct.

6. The method according to claim 5 , said method further comprising:

positioning said impeller adjacent said inlet opening.

7. A fuel equalization system, comprising:

a filter box for accepting an air stream and a fuel stream, said air stream and said fuel stream mixing to form a mixed air/fuel stream;

a blower;

a duct section having an outlet in fluid communication with an intake of said blower and having an inlet for accepting said mixed air/fuel stream from said filter box prior to said mixed air/fuel stream being presented to said blower;

a vaned impeller disposed within said duct section so as to receive air returned from said blower into said duct section; and

a substantially planar baffle extending along and substantially diametrically across the path of said mixed air/fuel stream, said baffle being fixedly positioned within said duct section and extending from the inlet of said duct section into said impeller, wherein said baffle permits an unobstructed and simultaneous flow of said mixed air/fuel stream on opposing sides of said baffle; and

wherein vanes of said vaned impeller and said baffle are configured to reduce the velocity and rotation of said returned air passing through said duct section.

8. The fuel equalization system recited by claim 7 , wherein:

said baffle substantially bisects said impeller.

9. The system according to claim 7 , wherein said impeller is movable together with said blower.

10. The system according to claim 7 , wherein said impeller is fixedly connected to said duct section.
