摘要： A fuel injection pump designed to deliver an amount of fuel divided into a pilot and a main injection volume, including a surface of a pump plunger which is guided within a pump cylinder, apart from two recesses limited by an inclined control edge, a first horizontal control edge is formed by a frontal shoulder; and on a side opposite the shoulder, it has a fully enclosed transverse groove with a second and third control edge. Two control apertures and an annular groove above them in the wall of the pump cylinder effect the control, in conjunction with the aforementioned control edges, of the precisely determinable pilot injection and, after a delivery interval, determined by the difference (b-a) between the width (b) of the transverse groove and the distance of the annular groove to the control aperture, the subsequent main injection. For the purpose of controlling an exact and largely speed-independent start of delivery of both the pilot and the main injection, the control apertures can be equipped with a straight limiting edge on the pump chamber side.

摘要： The invention is drawn to a pump having a piston which is reciprocable within a cylinder. The cylinder has a closed end including a liquid outlet and port means to introduce a liquid into the closed end of the cylinder. The piston has on its peripheral surface a helical groove means fluidly connected to the closed end of the cylinder and a second groove to communicate the port with the closed end of the cylinder when the piston is in a position between a location in which the port directly communicates with the closed end of the cylinder and a location in which the port communicates with the helical groove means. The second groove in the peripheral surface of the piston is located between the helical groove means and the part of the piston adjacent to the closed end of the cylinder. The second groove also communicates with a cutaway portion in the wall of the cylinder that is coaxial with the axis of the port.

摘要： A fuel injection pump for an internal combustion engine includes at least one pump piston movably disposed in a piston sleeve which piston sleeve is fitted in a pump housing. A first arrangement associated with the piston draws fuel through suction ports into a working chamber of the pump during a piston suction stroke. A second arrangement associated with the piston cuts off a connection to a suction side of the pump and thereafter initiates a delivery from the working chamber to an injection nozzle, which delivery is divided into two phases. The second arrangement is operable during a piston delivery stroke. A third arrangement controls the phases and includes the suction ports and an inside edge of the piston sleeve. The inside edge of the piston sleeve is provided on a planar end face of a guide bore of the sleeve and faces the working chamber.
