摘要： An inwardly opening fuel injection nozzle includes a first spring (21) which is coupled by means of a push rod (22) to the valve member (18) of the nozzle. The nozzle includes a second spring (28) positioned betweeen the first spring and the valve member and acting upon a slidable abutment member (29) which is engaged by the valve member (18) after a predetermined movement of the valve member away from a seating. The valve member is lifted against the first sprng by fuel under pressure supplied to an inlet (14) to allow restricted fuel flow through an outlet (16A) and further against the action of both springs as the pressure at the inlet increases to allow unrestricted flow through the outlet.

摘要： A fuel pumping apparatus for supplying fuel to an internal combustion engine comprises a rotary distributor member (10) mounting a pumping plunger (16) slidable in a bore (15) and moved inwardly to discharge fuel from the bore by cam lobes on the internal surface of a cam ring (28), the cam lobes acting on the plunger through a cam follower (26, 27). A valve (37) is provided which at a predetermined position during the inward movement of the plunger, is opened to lower the pressure in the bore and thereby to terminate fuel flow through an outlet (20). The valve is actuated by the cam lobes either from the cam follower or from the plunger.
