Abstract
1,014,191. Reciprocating pumps. SIMMS GROUP RESEARCH & DEVELOPMENT Ltd. March 30, 1962 [Feb. 6, 1961], No. 4410/61. Heading F1A. In a fuel injection pump the effective piston stroke length is controlled by a governor piston 15 in dependence on the rate of operation of the pumping assembly 1, 3. At each injection stroke fuel is forced by enlargement 11 through passages 12, 13, 16, 17 to unseat ball-valve 18 and thence through grooves 20a to emerge at face 20. Fluid pressure forces governor piston 15 to the left against the base of spring 3 to allow fuel, being pumped by piston 1 through passages 6, 7, 8, to be spilled-off when space 26 opens to passage 27. On the return stroke of piston 1 ball-valve 18 closes and fuel returns through a cut-away 21, adjustable by rotation of the governor piston 15, to passage 30. The amount of leakage which takes place determines the starting position of governor piston 15 at the next fuel injection stroke, so that less movement of governor piston 15 is required before spill occurs and fuel delivery is terminated at an earlier stage in the stroke of piston 1. An additional spill passage 27a is opened by end face 20 to give optimum governor action. Axial movement of plug 25 controls the maximum engine load and control rod 24 is withdrawn to increase the fuel supply for starting. The piston 1 is rotated to deliver fuel through other passages 8 (not shown) and helical grooves and a spill passage may be provided to control spill for the respective cylinders. Other inlet passages 5 may be provided.
