Title:
FUEL TANK VENTING CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2017/163661
Kind Code:
A1
Abstract:
A fuel tank venting control valve has a first valve and a second valve. The first valve is operated by a first float disposed in a first fuel tank. The second valve is operated by a second float disposed in a second fuel tank. The first float, the first fuel tank, the second float, and the second fuel tank are arranged in an inside and outside double configuration. The second valve is formed between the first float and the second float. The first float and the first fuel tank form a siphon passage. The siphon passage pushes fuel up toward the second fuel tank. The first fuel tank stabilizes the behavior of the first float. The second fuel tank stabilizes the behavior of the second float. A throttle passage and a relatively large through-hole suppress the pulsing vibration of the first float. The provided fuel tank venting control valve is compact.
