ABSTRACT:
A fuel pumping apparatus includes a control rod movable in an axial direction to vary the quantity of fuel delivered by the apparatus. A stop member is engageable with a part on the control rod to determine the normal maximum amount of fuel which can be supplied. The stop member can be moved laterally by a first spring to allow an excess of fuel to be supplied. A temperature responsive second spring opposes the action of the first spring, the second spring at normal operating temperature exerting a greater force than the first spring but when cold shrinking to allow movement of the stop member by the first spring.
