Claims

[Scope of utility model registration request]

a first chamber and a second chamber separated by a diaphragm;
an enrichment valve having a chamber, a fuel supply path that communicates with an introduction port provided in the first chamber and supplies fuel from a fuel supply source, and an enrichment valve that is connected to the diaphragm and opens and closes the introduction port; A fuel outlet path that communicates with the first chamber and guides the supplied fuel to the carburetor, and a fuel outlet that is accommodated in the second chamber and elastically presses the diaphragm so that the enrichment valve opens the inlet port. A manifold negative pressure path that communicates with a negative pressure port provided in the second chamber and applies negative pressure to the second chamber as the engine operates, wherein the fuel supply path is connected to a midway portion of the fuel supply path. 1. A fuel correction device comprising: a bypass path branching from the inlet port and communicating with an inlet port; and a thermo valve that opens and closes the bypass path depending on the temperature of engine cooling water.
