Abstract
There is disclosed a rotary distributor type liquid fuel injection pump for delivering measured charges of fuel under high pressure sequentially to the cylinders of an associated engine in timed relation therewith. The pump includes a movable metering valve for regulating the quantity of fuel in the charges. The metering valve also controls a normally closed bypass port which is opened by the metering valve as the metering valve approaches its closed position to continue the circulation of cool fuel from the supply tank through the pump whenever the metering valve is closed as during the downhill coasting of the vehicle on which the pump is mounted.
