Abstract: A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.

Abstract: A fuel injection pump for internal combustion engines has a simultaneously reciprocating and rotating pump piston which aspirates fuel from a fuel compartment and then delivers it under pressure to engine fuel lines. An electromagnetic valve can obturate the conduit between the fuel compartment and the pressure chamber of the pump, thereby shutting off fuel delivery. To permit manual override of this shut-off, the electromagnetic valve may be partially unscrewed from the pump housing, thereby lifting the valve closing member from its seat and permitting fuel flow. In another version, an externally accessible central valve bolt partially lifts the valve-closing member from its seat.

Abstract: An improved r.p.m. regulator of a fuel injection pump for internal combustion engines includes an improved control spring mechanism. The control spring mechanism is connected to one end of a control lever which in turn is connected at its other end to a fuel supply quantity setting member. The control lever serves to actuate the fuel supply quantity setting member in accordance with the forces applied to the control lever by the control spring mechanism and an r.p.m.-dependent force applying structure which applies a force to the control lever in opposition to the force applied by the control spring mechanism. The control spring mechanism includes a compression spring mounted between the control lever and a setting lever, a first connecting member and a second connecting member. The first connecting member is connected to that end of the control spring furthest from the setting lever, while the second connecting member is connected to that end of the control spring furthest from the control lever.

Abstract: A fuel injection pump which has a shutoff device for the fuel supply to the pump work chamber, comprising a magnetic valve, which controls an intake bore to the work chamber of the fuel injection pump. The fuel injection pump further has a relief conduit, which is connected by an annular slide on the pump piston with the suction chamber in order to terminate the effective supply stroke of the pump piston. In order to assure reliable shutoff of the fuel supply to the pump work chamber, a check valve is further disposed in the connection between the pump work chamber and the suction chamber, which check valve is closed, during the intake stroke of the pump piston, with the collaboration of the pressure drop from the suction chamber to the pump work chamber.

Abstract: There is proposed a speed governor for a fuel injection pump for internal combustion engines having a governor lever for setting the fuel injection quantity and a governor spring assembly arranged to engage the governor lever and counter to which an rpm-dependent force acts. To compensate for manufacturing tolerances of the governor spring assembly, it is also proposed that the effective length of a spring of the governor spring assembly be varied by realizing one of the supporting parts of the governor spring assembly as a multiple-part element. The supporting part is embodied such that it can be displaced by an adjusting lever in order to vary the pre-stressing of the governor spring, and that the first part is extended coaxially through it out of the interior of the fuel injection pump and can then be rotated in order to adjust the effective length of the governor spring and then fixed in an intended rotational position.
