Abstract (en)

A pump including a metering chamber (40) and a timing chamber (50) formed on either side of a floating piston (56) slidably mounted in an axially extending bore. An electromagnetic control valve (18) controls the discharge of fuel from the timing chamber (50) for creating a variable hydraulic link between a plunger (58) and the floating piston (56) to thereby control the injection timing. In order to vary the quantity of fuel stored in the metering chamber (40) during the downward movement of the floating piston (56), the control valve (18) is variably opened for the admission of fuel at supply pressure into the timing chamber (50), thereby arresting the metering piston (56) in a predetermined position.
