摘要： PURPOSE: To prevent vapor lock by positively separating gasified fuel from the vaporized gas by means of a small size gas/liquid separation chamber installed in the downstream of an ejection valve of a fuel pump.
CONSTITUTION: A diaphragm 5 is driven by a cam 1, which is interlocked to an engine. Fuel is sucked from a suction hole 7 and pressurized in pump chamber 9, and is forced to flow into a separation chamber 11 through an ejection valve 10, downstream of which the separation chamber 11 is provided. The cylindrical separation chamber 11 is composed of a reflector 11a and a side wall 11b. This side wall 11b is provided with a return passage 13 and an ejection nozzle 14; the former interflows with a fuel tank, not shown in the figure, while the latter interflows with a carburetor, not shown in the figure. On the ejection valve 10 within the chamber 11, a pipe 12a is provided forming a gap A to regulate the ejection speed. Owing to this fuel flow through the pipe 12a, gas/liquid separation is achieved.
