Abstract

PURPOSE: To facilitate the proper drive irrespectively of the temperature in the engine room by providing a passage conducting a space of a float chamber with the negative pressure source and by providing a thermosensitive valve body to open and close by upward and downward fluctuation of the temperature in the carburettor on the liquid level on this passage.
CONSTITUTION: In concurrence of providing a negative pressure passage 20 which opens an extremity in a space at more upward part than the liquid level in a float chamber 5 and the other extremity is connected to the negative pressure source, a thermosensitive valve body 10 installed on this negative pressure passage 20 and a throttle 21 with making the negative pressure passage 20 of the thermosensitive valve body 10 open and close by upward and downward fluctuation of the temperature in the carburettor 1, liquid fuel gain is controlled for being charged into the engine. The proper idle drive is obtained regardless of the situation of the engine driving condition, since said thermosensitive valve body 10 automatically opens and closes the negative pressure passage 20 by the temperature in the carburettor
