Abstract: The invention concerns a distributor fuel-injection pump for internal combustion engines, with a mechanical rpm controller in which a tensioning lever (28) and a starting lever (29) operate together as a control lever system in such a way that, above the idle rpm value they act as a compound system, the volume control element (13) being connected to the start lever and, in addition, the starting lever being acted on by an idler spring (31), the tension in which can be changed as a function of operating parameters in order to give a corresponding change in the quantity delivered when idling, for example in the event of an idling overload (caused by switching in electrically powered auxiliaries or when cold-starting).

Abstract: A process for manufacturing the movable element (117) of a pressure valve for fuel injection pumps by material removal. The movable element has a closing cone (123), a balance piston (128) an several fuel guiding recesses (125) extending in the axial direction of a guiding shaft (118). Several such elements (117) are simultaneously produced from a previously hardened bar, the rotation-symmetric notches (131) and openings being effected in a known manner by turning tools, whereas the recesses (125) are for example produced by rotating tools, in particular grinding tools, transversely moved with respect to the axis of the bar.

Abstract: A pressure relief valve (16) for fuel injection pumps has a relief piston (28) that plunges into a guiding bore (19) of a valve support (21) in order to relieve the pressure in the pressure duct. The valve element (17) has recesses (25) upstream or downstream of the relief piston (28), available to the fuel duct when the valve is open and arranged in a shaft (18) that guides the movable valve element (17) in the guiding bore (19). The lands (27) of the shaft (18) that delimit the recesses (25) merge directly into the relief piston (28), so that the front walls of the recesses (25) form at the same time the front wall of the relief piston (28).

Abstract: A fuel injection pump for internal combustion engines has an adjusting piston (11) for adjusting the injection timing which delimits a working space (14) in a cylinder (12). A mobile spool valve (18) which is actuated by a supply pressure is arranged in a blind bore (17) in the adjusting piston (11) and delimits a compression chamber (21). Depending on the setting of the spool valve (18), the working space (14) is connected to the compression chamber (21) or to a discharge chamber (15). The feed pressure is generated by a pump (33) and modified by a solenoid valve (46) in an outlet line (44) in function of operating parameters of the internal combustion engine in such a manner that the injection timing is adjusted in function of the operating parameters.

Abstract: A fuel injection pump for internal combustion engines has a delivery rate adjusting element (11) which can be adjusted by means of a starting lever (13) as well as adjusting lever (20) and a clamping lever (15). The starting lever (13) abuts, via a starting spring (16), on the clamping lever (15) and rests against a stop lever (17) when the engine is at rest. To set an optimal quantity of injected fuel when the engine is started, which must be less for a warm start than for a cold start, the stop lever (17) is force-coupled with the adjusting lever (20) so that, when the adjusting lever (20) pivots, the stop lever (17) moves from a first to a second end position. The end positions are such that the stop lever (17) forces the starting lever into a position which, in the first end position, sets a quantity of fuel required for a warm start and in the second end position a quantity of fuel required for a cold start on the delivery rate adjusting element (11).

Abstract: A fuel injection pump for internal combustion engines with a control lever (36) acting as a fuel quantity adjuster which, on full load, butts against one arm of a swivelling, two-armed stop lever (41). The other arm of the lever is supported on an operating member (44) which can be electrically heated and changes its position depending on the temperature. The operating member (44) is included in an electric circuit (52) which is closed by a switching component (53) subjected to atmospheric pressure when that pressure drops below a given value. The movement of the stop lever (41) caused by the operating member is limited to a predetermined value by a counter-stop (49).
