<p>A liquid fuel injection pumping apparatus of the axially slidable rotor type includes a low pressure supply pump which supplies fuel to an injection pump including pumping plungers mounted in a rotary distributor member. A surface of the distributor member is located within a chamber to which a control pressure can be supplied by way of a control valve from the outlet of the low pressure pump. The distributor member is moved by increasing control pressure against a spring to reduce the amount of fuel supplied by the injection pump. A valve is provided which is responsive to the pressure drop across the control valve, the valve acting to prevent flow of fuel to the injection pump in the event that the pressure drop across the control valve falls below a predetermined value.</p> |
