燃料補正装置。 an enrichment chamber divided into two chambers by a diaphragm; an auxiliary fuel supply path to a carburetor communicating with one chamber side of the enrichment; an enrichment valve connected to the diaphragm for opening and closing the auxiliary fuel supply path; A spring that is housed in another chamber and presses the diaphragm, a manifold negative pressure path that communicates with this chamber and forms a negative pressure chamber, and a manifold negative pressure path that communicates with this chamber to form a negative pressure chamber, and detects the temperature of the engine cooling water and opens to the atmosphere when the pressure is below the set pressure and is closed when the pressure is above the set pressure. a water temperature control path that communicates the thermovalve with the negative pressure chamber of the enrichment and is provided with a vacuum switching valve in the middle, and a water temperature control path that connects the water temperature control path to the vacuum switching valve. 1. A fuel correction device for a carburetor, comprising a vacuum transmitting valve and a bypass passage communicating with a midway portion of the manifold negative pressure passage.
