What is the function of the float chamber?
A float chamber is a device for automatically regulating the supply of a liquid to a system. It is most typically found in the carburettor of an internal combustion engine, where it automatically meters the fuel supply to the engine.
How is fuel drawn from the float chamber?
The float chamber actually works similarly to a toilet tank. The floats essentially “float” on the fuel in the float chamber. When fuel is drawn up the main jet, the fuel level in the chamber drops, thus the float also drops. This opens the needle valve allowing more fuel to enter the chamber.
What happens when fuel is fed into the float chamber?
When fuel is fed into the float chamber it rises and the float shuts off the needle valve. If, however, the chamber air vent is blocked, the fuel rising compresses the air in the chamber and fuel is forced out of the jet at pump pressure.
