Abstract
A fuel pumping apparatus for supplying fuel to a compression ignition engine includes a high pressure pump to which fuel is supplied by a low pressure pump by way of a throttle which is responsive to the output pressure of the low pressure pump for the purpose of providing a governing action. A valve is connected in series with the pumps and is energized to the open position through a pressure responsive switch which closes when the output pressure of the low pressure pump is above a predetermined value. Means is provided to energize the valve for the purpose of starting the associated engine.
