LIQUID FUEL FEEDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a liquid fuel feeding apparatus for feeding liquid fuel to a fuel tank by a suction pump which can surely stop to drive the suction pump even in the case that a micro computer causes malfunction. SOLUTION: A liquid level detection means 9 for the micro computer and a liquid level detection means 10 for input of pump drive means are provided to detect height of liquid level of the fuel tank 2. A signal the liquid level detection means 9 for the micro computer detected is sent to the micro computer 8 and a signal the liquid level detection means 10 for input of pump drive means is sent to a pump drive means 8 for driving the suction pump 6 not through the micro computer 8. Thus, the suction pump 6 is surely stopped to drive in the case that a signal to stop the pump drive means 7 is not sent by malfunction of the micro computer 8. COPYRIGHT: (C)2006,JPO&NCIPI
