AIRCRAFT TANK FUEL PICK-UP VALVES IN FUEL TRANSFER LINES

摘要

This invented valve finds its applicability as fuel pick-ups coming in fuel transfer circuit in the civil aircrafts and military aircrafts which are having non pressurised fuel tanks. A new, economical, reliable and simple 'Fuel Pick-up valve' has been invented using simple ball-gravity principle to allow fuel transfer in all aircraft attitudes including inverted flying without any discontinuity. Refueling does not need any electrical energizing of the valve. It performs satisfactorily even with contaminated fuel. Transfer line and refueling line uses common single line when this valve is used; results in less piping and system weight reduction.
