Carburetor

A carburetor, for use in association with a liquid fuel powered engine in a vehicle comprising:

• a cylindrical barrel means having a bore-defining wall means, defining a bore therethrough, a central carburetor axis, an upstream end and a downstream end and a forward and rearward side;
• an annular ridge member forming a constriction in said barrel means and having an upstream and a downstream side;
• a dissipator body member of generally elongated globular pear-like shape located downstream of said annular ridge member and having a maximum cross-section transverse to said barrel means complementary to said annular ridge member, said body member being mounted coaxially with said central carburetor axis and being adapted to close said barrel means in the region of said downstream side of said annular ridge member;
• a plurality of radial fuel dissipating passageways formed through said body member for delivering fuel to the outer surface of said body member downstream of said ridge member said passageways comprising a forward group and a rearward group wherein there are a greater number of said passageways in said forward group and a lesser number of said passageways in said rearward group;
• one of said ridge member and said dissipator body member being movable relative to the other;
• movement means for moving said moveable one of said ridge member and said dissipator body member, whereby to establish an annular air passage between said body member, and said downstream side of said annular ridge member whereby air flowing in said barrel means from said upstream end to said downstream end is forced to flow first through said constriction and then around said maximum cross-section of said body member and,
• fuel line means connecting said fuel dissipating passageways for receiving said liquid fuel.
