摘要： An apparatus for supplying fuel in a fuel tank to an engine through a diaphragm type carburetor includes a fuel pump and an exhaust passage. The fuel pump includes a suction valve and a discharge valve and is driven by pulsation pressure caused by rotation of an engine. The fuel pump has a discharge port connected with a fuel inlet of the carburetor. At least one of the suction valve and the discharge valve of the fuel pump is so located as to be immersed in fuel of the same level as that of the fuel tank. The exhaust passage has one end communicating with a position between the fuel inlet of the carburetor and a diaphragm chamber and the other end communicating with the fuel tank.

摘要： An enrichment device for a charge forming system for an internal combustion engine that is responsive to induction system pressure for effecting a pumping action to draw fluid in when the engine is operating in a steady state condition and to discharge fluid for enrichment when the engine is being accelerated. The system includes a series of interrelated pressure sensing chambers for controlling the operation of the pump to avoid fluctuations during small variations in induction system pressure but to permit rapid and immediate pumping action upon sudden pressure changes.

摘要： A starting fuel supplying apparatus improves restarting performance of an engine in a warm-up state. In the engine in which a carburetor is disposed on the side of the cylinder, the starting fuel supplying apparatus and a thermo-sensitive member attached to the carburetor are disposed on the side of the carburetor close to the engine.
