Abstract
An improved apparatus is disclosed for controlling the flow of liquid fuel through a feed tube onto the convex exterior surface of an atomizer bulb of the Babbington type. Liquid fuel is directed into a deaeration chamber (50) having a suitable baffle for separating entrained air and dissipating dynamic flow effects. The inlet (64) of the feed tube for the atomizer bulb is positioned at the lower end (54) of the deaeration chamber so that as the chamber fills with liquid fuel, any air in the feed tube is quickly flushed. The upper end of the deaeration chamber is closed and provided with an inlet (56, 104) to a conduit (58). An adjustment (62; 72-88; 90-126) is provided to permit variation of the flow through the suction conduit and, hence, variation of the flow over the atomization bulb. To provide a constant flow rate of atomized fuel leaving the aperture even as the temperature of the fuel varies, a temperature sensitive valve (66; 128-138) may be provided at the outlet of the pump with a suitable bypass (68) to the sump or in the suction conduit (70) or in both locations. Methods of delivering liquid fuel are disclosed.
