ABSTRACT:
A fuel system bubble dissipation device wherein fuel is delivered through a fuel line from a fuel tank to an engine. The device includes an ejector having a casing with a fuel flow passage connected into the fuel line and a nozzle extending into said fuel flow passage. The nozzle is supplied with pressurized fuel to induce a higher pressure in the fuel flowing through the ejector. A bubble accumulation chamber is associated with the fuel line and the ejector to provide a reservoir for fuel for passage to the ejector and hold an air bubble separated from and above the fuel and a bubble evacuation passage connects the upper end of the bubble accumulation chamber to the fuel flow passage of the ejector whereby air and vapor can be drawn from the upper end of the bubble accumulation chamber and mixed with fuel flowing through the ejector. The bubble evacuation passage is of a size to control the rate at which air and vapor are drawn from the bubble accumulation chamber.
