Abstract
A liquid fuel injection pumping apparatus includes a fluid pressure operable piston coupled to a timing component of the apparatus. A first spring is provided to bias the piston towards a retard position. A pair of abutments are provided at the ends of the first spring and adjusting means is provided to determine the spacing of the abutments. The adjusting means is controlled by a first control means the setting of which is varied with temperature. A second spring acts on the piston and is located between one of the abutments and the piston and second control means adjusted in accordance with the setting of the fuel control of the apparatus, is provided to determine the axial setting of the adjusting means.
