Abstract

707,904. Centrifugal governors; rotary gear pumps. CUMMINS ENGINE CO., Inc May 28, 1951 [July 6. 1950], No. 12449/51. Classes 57 and 110(2) [Also in Group XXVII] A slide valve 53 controlling the fuel supply to the injectors of an internal-combustion engine is actuated by a centrifugal governor 85 comprising a pair of main weights 87 and a pair of idling weights 86, the valve 53 being loaded through a rocker 96 by an idling spring 110 and a maximum speed spring 115. When the engine speed rises above idling the governor overcomes the idling- spring 110 and moves the valve 53 to cut ofl an idling fuel passage 83. Further movement outwards of the idling weights 86 is prevented by projections 1-12 thereon and when maximum engine speed is reached the spring 115 is overcome by the main weights 87 and the valve 53 moved to cut off the main fuel passage 72. The fuel is fed to the valve 53 by a pair of coaxially-arranged gear-wheel pumps 27, 41, driven from the driving shaft 120 of the governor 85, and a spring-loaded by-pass valve 63 associated with the pump 41 is arranged so that the output pressure of the pump decreases with decreasing engine speed. The valve 63 comprises a hollow cup with a series of holes 69 arranged on a helix which are uncovered in succession.
