Abstract

PURPOSE: To permit feeding of fuel for acceleration according to temperature, by forming the diaphragm-type accelerator pump of a carburetor which consists of two diaphragms and sealing-in, between the both diaphragms, the riguid which varies volume according to temperature.
CONSTITUTION: An accelerator pump consists of the first and second diaphragms 21 and 23, and between them, a fuel chamber 24, intermediate chamber 25, and an intake negative pressure chamber 30 are separately formed. The fuel introduced into the fuel chamber 24 from a float chamber 18 is jetted from an accelerating nozzle 36, and the intake negative pressure is introduced into the negative pressure chamber 30 through a port 28, and both diaphragms are operated. Further, into the intermediate chamber 25, the liquid having a large thermal expansion rate is sealed-in, and volume is varied according to the temperature, and thus amount of acceleration fuel can be varied.
