Abstract

Abstract A fuel system for internal combustion engines comprising a manifold having an inlet passage for a fuel mixture and a plurality of outlet passages to the cylinders of the engine. A fuel mixture distributing device is provided adjacent the inlet passage and comprises a plurality of closely packed sinuous members defining a plurality of generally axially extending twisted passages which are laterally intercommunicating.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 151 words
In an intake manifold having an inlet passage for a fuel mixture and a plurality of outlet passages, a fuel mixture distributing device mounted adjacent said inlet passage and extending in the direction toward said outlet passages, said device comprising a plurality of generally parallel closely spaced sinuous members in lateral side-by-side relation defining a plurality of radially spaced generally axially extending twisted paths, said paths being non-uniform but laterally intercommunicating whereby a fuel mixture flowing axially through said device is caused to move through a plurality of laterally spaced interconnected axially extending non-uniform paths to effect turbulence of the fuel mixture and whereby droplets of fuel mixture are prevented from moving through the device along the walls of a manifold, said members being made from a spirally wound single piece comprising a plurality of parallel slits defining each said member, each said member being thereafter twisted to the final form.
Claim 2
Dependent Claim 151 words
In an intake manifold having an inlet passage for a fuel mixture and a plurality of outlet passages, a fuel mixture distributing device mounted adjacent said inlet passage and extending in the direction toward said outlet passages, said device comprising a plurality of generally parallel closely spaced sinuous members in lateral side-by-side relation defining a plurality of radially spaced generally axially extending twisted paths, said paths being non-uniform but laterally intercommunicating whereby a fuel mixture flowing axially through said device is caused to move through a plurality of laterally spaced interconnected axially extending non-uniform paths to effect turbulence of the fuel mixture and whereby droplets of fuel mixture are prevented from moving through the device along the walls of a manifold, said members being made from a spirally wound single piece comprising a plurality of parallel slits defining each said member, each said member being thereafter twisted to the final form.
Claim 3
Dependent Claim 22 words
The combination set forth in claim 1 wherein the ends of said members remote from said inlet passage are free and unconnected.
Claim 4
Dependent Claim 14 words
The combination set forth in claim 1 wherein said members have the same pitch.
Claim 5
Dependent Claim 17 words
The combination set forth in claim 1 wherein each said member is twisted in the same direction.
Claim 6
Dependent Claim 159 words
For use in an intake manifold having an inlet passage for a fuel mixture and a plurality of outlet passages, a generally circular fuel mixture distributing device having its inlet mounted adjacent said inlet passage and having a large portion extending into the manifold, said device comprising a plurality of generally parallel closely radially spaced sinuous members in lateral side-by-side relation defining a plurality of generally axially extending twisted paths, said paths being laterally intercommunicating whereby a fuel mixture flowing axially through said device is caused to move through a plurality of laterally spaced interconnected axially extending non-uniform paths to effect turbulence of the fuel mixture and whereby droplets of fuel mixture are prevented from moving along the outside of the device and along the walls of a manifold, said members being made from a spirally wound single piece comprising a plurality of parallel slits defining each said member, each said member being thereafter twisted to the final form.
Claim 7
Dependent Claim 159 words
For use in an intake manifold having an inlet passage for a fuel mixture and a plurality of outlet passages, a generally circular fuel mixture distributing device having its inlet mounted adjacent said inlet passage and having a large portion extending into the manifold, said device comprising a plurality of generally parallel closely radially spaced sinuous members in lateral side-by-side relation defining a plurality of generally axially extending twisted paths, said paths being laterally intercommunicating whereby a fuel mixture flowing axially through said device is caused to move through a plurality of laterally spaced interconnected axially extending non-uniform paths to effect turbulence of the fuel mixture and whereby droplets of fuel mixture are prevented from moving along the outside of the device and along the walls of a manifold, said members being made from a spirally wound single piece comprising a plurality of parallel slits defining each said member, each said member being thereafter twisted to the final form.
Claim 8
Dependent Claim 22 words
The combination set forth in claim 5 wherein the ends of said members remote from said inlet passage are free and unconnected.
Claim 9
Dependent Claim 14 words
The combination set forth in claim 5 wherein said members have the same pitch.
Claim 10
Dependent Claim 17 words
The combination set forth in claim 5 wherein each said member is twisted in the same direction.
Claim 11
Dependent Claim 161 words
For use in an intake manifold having an inlet passage for a fuel mixture and a plurality of outlet passages, a generally circular fuel mixture distributing device having its inlet mounted adjacent said inlet passage and having a large portion extending into the manifold, said device comprising a plurality of parallel closely radially spaced sinuous members in lateral closely spaced side-by-side relation adapted to fill substantially the entire area of said inlet passage and defining a plurality of axially extending twisted paths, said paths being laterAlly intercommunicating and the spaces between adjacent sinuous members being unrestricted in an axial direction throughout the lengths of said sinuous members whereby a fuel mixture flowing axially through said device is caused to move through a plurality of laterally spaced interconnected axially extending non-uniform paths to effect turbulence of the fuel mixture and whereby droplets of fuel mixture are prevented from moving along the outside of the device and along the walls of a manifold.
Claim 12
Dependent Claim 161 words
