Abstract: A fuel injection pump for internal combustion engines has a reciprocated pump plunger (3) and a control slide (5), which is displaceable on the latter, and comprises a control borehole (28) which cooperates with a helical groove (15) on the pump plunger (3), the helical groove (15) communicates with the pump work space (26) via a duct (24, 25). For the purpose of controlling the start of delivery, the helical groove (15) communicates with a cylindrical counterbore (21) at the end area (22) remote of the pump work space. Moreover, the end area (23) of the control groove (15), which end area (23) is close to the pump work space, can communicate with a second counterbore in order to ensure a zero delivery when the helical grooves (15) are relatively flat.

Abstract: A fuel injection pump for internal combustion engines, in which at least during normal engine operation the injection quantity is effected by controlling a fuel quantity control conduit which is provided in the pump piston in communication with the pump work chamber, via a control slide that is displaceable on the pump piston in cooperation with fuel quantity control openings, the axial position of the control slide determining the onset and end of supply. The earliest possible supply onset is further determined by a supply onset control opening disposed in the pump piston, which opening is sealed by entering into the cylinder liner after a pre-determined stroke extent has been traversed. Subsequent to this entry, an injection pressure can build up in the pump work chamber.

Abstract: The roller shaft which actuates a pumping element in a fuel injection pump is secured against unintentional release during transport by elastic elements, preferably spring wire parts, whose one end engages a stationary portion of the fuel supply pump and whose other end engages a recess or cutout in the roller shaft and cooperates with a shoulder or stop therein to prevent unintentional drop-out while permitting a normal reciprocating motion after installation. Suitable openings and grooves provided in the roller shaft guide can hold and orient the spring wire.

Abstract: A fuel injection pump for internal combustion engines, having a plurality of in-line pump elements in which the supply onset is effected by means of control slides, one of which is axially displaceable on each of the pump pistons and by controlling relief conduits of the pump work chambers. The control slides are actuated via a torque shaft in that via driver tangs which are secured to the torque shaft by fastening parts screwed to the torque shaft, the control slides are axially displaced upon rotation of the torque shaft. For adjusting the stroke or axial position of the individual control slides to one another, spacer means, in particular shims are provided between the fastening part and the torque shaft in the stroke direction of the control slides.

Abstract: A pressure valve is proposed herein which is built into the injection pump, its valve closing body being guided in a valve carrier, and arranged to open in the supply direction of the fuel, counter to the force of a restoring spring. A check valve is built into the pressure valve, its valve seat carrier being secured to the valve closing body and its movable valve closing member is arranged to open counter to the supply direction of the fuel via a spring supported on the base of the valve closing body. For axially securing the valve seat carrier on the valve closing body, the restoring spring simultaneously engages the valve seat carrier. As a result, the satisfactory functioning of the check valve is assured.

Abstract: A fuel injection pump for internal combustion engines is disclosed, in which a profiled governor rod of a supply quantity adjusting member, the latter controlled by a final control element, is extended at its end toward the final control element out of the pump housing and is supported in a displaceable manner at the point where it emerges. For the sake of sealing the support point, a cylindrical slide bearing sheath is secured in the pump housing at the location where the governor rod emerges from the pump housing. A cylindrical governor rod guide means which is joined to the profiled governor rod and closes it off or surrounds it in a sealing manner is guided displaceably, with the least possible play, in the slide bearing sheath.
