Abstract
A combined lift and metering pump includes a set of relatively rotating pump elements in the form of an outer gear and a eccentrically disposed inner gear fixed on a drive shaft. A regulator communicates through a control passage with a discharge chamber of the pump to regulate fuel pressure in the discharge chamber and a metering orifice formed through the outer gear provides for intermittent communication with a timing port once with each revolution of the outer gear for discharging a metered amount of fuel from the discharge chamber.
