FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to diaphragm carburetors for internal combustion engines of petrol tools. Proposed diaphragm carburetor of internal combustion engine has body with main air channel accommodating choke and throttle valves, fuel chamber with diaphragm mechanism connected to fuel feed channel with valve and lever installed at channel outlet, main metering system with check valve, idling system communicating with fuel chamber, and fuel pump. Atomizer is installed in venture of main air channel at outlet of fuel channel of main metering system. Passage area of atomizer hole is 0.4-0.6 passage area of carburetor main metering system fuel channel.
EFFECT: simplified design, increased pickup of engine and reliability.
