Abstract

A hot restart valve 64, (120) Fig. 2 (not shown) generally for use with a diaphragm carburetor 10 has a control chamber 68 and a vapor discharge chamber 66 separated by a spring biased diaphragm. The vapor discharge chamber communicates with the fuel chamber 26 of the carburetor and a vapor venting port 76 has a movable, normally-open vent valve 78. The control chamber 68 monitors air flow through the carburetor induction passage via a signal port 94, and activates the diaphragm 70 to which the vent valve is connected in responsive to the air flow. During engine operation the vent valve 78 is drawn in to seal the vapor venting port 76, and at engine shutdown the valve 78 opens to allow evacuation of vapor from the fuel chamber of the carburetor. <IMAGE>
