Abstract
Abstract A device for intimately intermixing a liquid fuel, air, and preferably also a metered proportion of water, for delivery to an internal combustion engine or other fuel burning mechanism, the device including a rotor to which the fuel and water are delivered for centrifugal discharge radially outwardly in finely divided mist form, with the rotor preferably carrying a large number of minute fibers projecting radially outwardly and along which the liquids flow in a manner subdividing the liquids into minute droplets. The rate of delivery of the fuel and water is regulated in accordance with the rate of flow of air through the device, and by a control structure actuable by the air.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
309 words
A fuel feed device comprising a hollow housing through which air flows in passing to a fuel burning unit; a throttle valve for regulating the rate of flow of air through said housing; a rotor in the housing along the path of air flow therethrough and operable to feed fuel into the air for admixture with the air; a motor for driving said rotor rapidly about an axis and energized by power other than the power of air flowing through the housing; an element, in addition to said rotor and the other previously recited elements, positioned in the path of said air flow and deflectible by the flowing air to positions varying in accordance with the rate of air flow through the housing; means for delivering liquid fuel to said rotor at a location to be fed thereby into said flow of air, said last mentioned means including valve means actuable by said element to regulate the rate of fuel delivery to the rotor in accordance with said deflection of said element; a plate mounting said motor and rotor and disposed generally horIzontally across the path of said air, said plate containing a series of circularly spaced apertures generally about the location of said motor and rotor; said element being essentially annular and disposed at the underside of said plate in a position closing said apertures and mounted to swing downwardly about essentially one side edge of the element to open the apertures; spring means yieldingly urging said element upwardly to closed position; said valve means including a flexible pinch valve body containing a passage for said fuel and a second passage for delivering water to said rotor for admixture with the fuel and air; and mechanism actuable by said element to close said passages in the pinch valve body in response to upward swinging movement of said element.

A fuel feed device comprising a hollow housing through which air flows in passing to a fuel burning unit; a throttle valve for regulating the rate of flow of air through said housing; a rotor in the housing along the path of air flow therethrough and operable to feed fuel into the air for admixture with the air; a motor for driving said rotor rapidly about an axis and energized by power other than the power of air flowing through the housing; an element, in addition to said rotor and the other previously recited elements, positioned in the path of said air flow and deflectible by the flowing air to positions varying in accordance with the rate of air flow through the housing; means for delivering liquid fuel to said rotor at a location to be fed thereby into said flow of air, said last mentioned means including valve means actuable by said element to regulate the rate of fuel delivery to the rotor in accordance with said deflection of said element; a plate mounting said motor and rotor and disposed generally horIzontally across the path of said air, said plate containing a series of circularly spaced apertures generally about the location of said motor and rotor; said element being essentially annular and disposed at the underside of said plate in a position closing said apertures and mounted to swing downwardly about essentially one side edge of the element to open the apertures; spring means yieldingly urging said element upwardly to closed position; said valve means including a flexible pinch valve body containing a passage for said fuel and a second passage for delivering water to said rotor for admixture with the fuel and air; and mechanism actuable by said element to close said passages in the pinch valve body in response to upward swinging movement of said element.
Claim 3
Dependent Claim
47 words
A fuel feed device as recited in claim 1, in which said mechanism includes a lever mounted pivotally to the underside of said plate and having a first end deflectible downwardly by said element and a second end adapted to engage and deform said pinch valve body.
