Title:
GAS TROUBLE PREVENTING DEVICE
Document Type and Number:
Japanese Patent JPS6263299
Kind Code:
A
Abstract:
PURPOSE:To shut off a gas passage even when a battery voltage is decreased, by a method wherein, by means of a shut off signal provided when the voltage of the battery is decreased to below a given valve and a shut off signal from a shut off deciding part, a shut off part is actuated. CONSTITUTION:The voltage of a battery 6 is inputted to a low voltage detecting part 12, and when the voltage of the battery is decreased to below a given value, the low voltage detecting part 12 outputs a shut off signal to a shut off part 10. By means of the shut off signal, the shut off part 10 shuts off a gas passage 1. In this case, since a shut off display part 9 is not actuated, no shut off display is effected to the outside. Thus, an instable side state is prevented from occurring resulting from continuance of a drop in the voltage of the battery, shut off without display takes place, and a user enables easy recognition of a fact that shut off is effected due to a drop in the voltage of the battery.
