TODAY’S PATENT – FUEL SUPPLY SYSTEM

The FUEL SUPPLY SYSTEM was invented by Geoffrey C. Todd (Evesham) on the 15^th  of June 1982 , bearing patent number US4334406A.

The present invention sets out to provide a liquid fuel supply system which is capable of accommodating some failure within the system without causing failure of the engine to operate correctly.

A liquid fuel supply system for an engine having a power demand adjuster, e.g. a manually operable control acting in conjunction with operational factors associated with the engine to determine fuel flow to the engine, in which apparatus is provided responsive to failure of part of the fuel system to cause an auxiliary to become effective to control fuel flow to the engine in accordance with the setting of the power demand adjuster, the arrangement being that for any setting of the power demand adjuster the fuel flow to the engine will not alter instantaneously when the auxiliary becomes effective to control fuel flow. It may be arranged that the relationship between fuel flow to the engine and the setting of the power demand adjuster may alter within a short period after the auxiliary has become effective.
