Fuel and air injection device

Claim 2

A fuel metering device for providing a controlled flow of fuel from a fuel outlet port comprising a body portion, fuel valve means and a fuel chamber in said body portion, said fuel valve adapted to intermittently admit fuel to said fuel chamber, said fuel chamber partly defining a fuel flow path to said fuel port, a fuel dispersing element in said chamber having a dividing portion disposed in said fuel path on the upstream side of said fuel port, said element including internal air passage means extending therethrough, and said air passage means emitting air in said fuel port centrally of said fuel flow path at said fuel port.

Claim 3

A fuel metering device as claimed in claim 1 wherein said dividing portion comprises a conical surface.

Claim 4

A fuel metering device as claimed in claim 1 wherein said body portion has an air passage connected to said element to supply air thereto, said fuel valve means adapted to open said air passage when fuel is being admitted to said fuel chamber.

Claim 5

A distributing and dividing element adapted for use in a fuel metering mechanism; said element constructed to be placed in a chamber in a fuel path; said element having an outer annular hollow section, a conical surface disposed in said fuel path, a central hollow tubular portion extending in the direction of the fuel path, and a series of hollow radial spokes connecting said annular section and said tubular portion; the annular surface adapted to closely fit the interior wall of said chamber; means in said wall supplying air to the interior of said annular section and thereby to said tubular portion whereby said conical surface will disperse the fuel flowing in said path into fine particles which are mixed with the air being admitted through said tubular portion whereby a proper mixture is produced for supply to combustion chambers of an internal combustion engine.

Claim 6

A distributing and dividing element adapted for use in a fuel metering mechanism; said element constructed to be placed in a chamber in a fuel path; said element having an outer annular hollow section, a conical surface disposed in said fuel path, a central hollow tubular portion extending in the direction of the fuel path, and a series of hollow radial spokes connecting said annular section and said tubular portion; the annular surface adapted to closely fit the interior wall of said chamber; means in said wall supplying air to the interior of said annular section and thereby to said tubular portion whereby said conical surface will disperse the fuel flowing in said path into fine particles which are mixed with the air being admitted through said tubular portion whereby a proper mixture is produced for supply to combustion chambers of an internal combustion engine.
