Float-Controlled Apparatus TRIZ Cases

Six fasteners with integrated and locking washers evenly compress the carburetor bowl gasket to prevent dry-out, leaks, and early repairs.

A vent-to-tank pipeline returns overflow fuel to the tank during storage, preventing carburetor leakage, corrosion, and clogging.

Stacked mesh refines fuel by impact scattering, improving particle quality while modular parts simplify assembly in carburetors and injectors.

A linked switch and valve close the main jet before tip-over, preventing fuel leakage.

A rollover shutoff valve assembly uses gravity-driven plugs to block fuel passages in inverted carburetors.

A secondary fuel tank positioned higher than the primary tank vents trapped air via buoyancy, resolving starting failures after refueling.

A carburetor fuel control device uses a segmented needle valve with a cylindrical metering portion to regulate flow area.

A diaphragm fuel pump driven by crank chamber pressure fluctuations supplies fuel via a communicating diaphragm chamber.

A carburetor filter removes particulate matter from fuel before it enters the secondary circuit to ensure smooth operation.

Radial groove on valve stem minimizes second bleed air passage length, preventing dirt attachment and simplifying processing.

A fuel supply device uses a bypass passage to deliver fuel directly to the carburetor before pump activation.

A modular fuel bowl system uses a removable flow assembly to simplify carburetor alignment and reduce misalignment errors.
