Abstract
A fuel metering device for providing a controlled flow of fuel from a fuel outlet port comprising a body portion, having a fuel valve therein adapted to intermittently admit fuel to a fuel chamber. The fuel chamber partly defines a fuel flow path to the fuel port and a fuel dispersing element is provided in the chamber having a conical dividing surface disposed in the fuel path on the upstream side of the fuel port. The fuel dispersing element includes internal air passages extending through same, the air passage means emitting air in the fuel port centrally of the fuel flow path at the fuel outlet port.
Claims4
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.
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.
