System for preventing fire danger in light aircraft from leaking carburettor fuel comprises drip tray with tube to carry fuel into engine air feed pipe

摘要

The system consists of a tray with a base (1) and raised sides (2, 3) and a rigid connector (4) that allows the tray to be connected by a supple tube (5) 4 - 8 mm in diameter to the engine air feed pipe before or after its air filter. The tray is larger than the area of the carburettor, with sloping sides to increase its collecting surface, and any fuel that drips into the tray from the carburettor is drawn through the tube by the air flow in the feed pipe.
