摘要： 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.

摘要： An rpm regulator of a fuel injection pump for internal combustion engine includes a single-arm drag lever and an intermediate lever which are bent to define a space into which a compression spring extends. The stroke of the compression spring is limited in both directions by stops defined by the intermediate lever and the drag lever, respectively. The regulator also includes a control spring arrangement which engages one end of the drag lever, a fuel quantity setting member which engages one end of the intermediate lever and controls due to its movement the quantity of fuel delivered by the fuel pump and an rpm governor which exerts an rpm defendent force against the intermediate lever in opposition to the force of the control spring arrangement. With this regulator the pump can deliver an excess fuel quantity for starting purposes and an automatically reduced normal fuel injection quantity when the rpm increases. This result is accomplished without increasing the dimensions of the fuel pump.

摘要： A fuel injection system is proposed which has a high-pressure pump, a fuel reservoir determining the injection pressure, and an intermediate piston, during whose first half-stroke meters fuel under low pressure and during a second half-stroke, driven by the reservoir, injects the metered fuel. In order to vary the duration of injection, the pressure in the reservoir is determined either by means of the supply quantity of the high-pressure pump or by means of an appropriate pressure control valve in an outflow conduit.

摘要： The invention relates to a fuel injection pump for internal combustion engines having an injection onset adjuster with which the injection onset is adjustable toward "early", for instance in accordance with temperature. In accordance with the invention this adjustment toward "early" is made possible especially in pumps having a load-dependent injection onset adjustment, which preferably exhibit a shift toward "late" up to full load.

摘要： 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 in one embodiment of the invention includes axially aligned tandem springs mounted between the control lever and a setting lever, a first connecting member and a second connecting member. In another embodiment of the invention a single spring is mounted between the control lever and a setting lever and tandem springs are mounted adjacent to one end of the second connecting member in a perforated pot that is associated with the control lever.

摘要： A fuel injection pump having a device for adjusting the injection timing having a work chamber defined by an adjusting piston and communicating via a throttle bore with a pressure source from which the pressure to adjust the adjusting piston is drawn. In order to modify the pressure in the work chamber, the work chamber can be made to communicate via a pressure limiting valve with the relief side of the pump. The control force of the pressure limiting valve is adjustable by means of a stepping motor. An influence on the pressure controlling the adjusting piston is thereby obtained which is restricted to the work chamber.

摘要： To provide for accurate alignment of a housing (10) retaining a fuel injection element (12, 15), and a second housing (23) retaining a control element controlling a function of the fuel injection element, in which the relative positions of the pump housing (10) and of the control element housing (23) are determinative of adjustment and alignment of interengagement between the injection element and the control element, the two housings are provided with attachment screws to attach them securely together, while permitting respective removal, for example for replacement of a sealing gasket (26), and to insure precisely aligned re-assembly, the housings include position locating means (27-34, 35') such as interengaging projection-and-recess means (40, 50, 60, 70, 80, 90, 100, 110; 37, 47, 57, 67, 77, 87, 97, 107) which accurately position the housings with respect to each other, and which are positionable after the housings have been first assembled and aligned to provide for said adjusted and aligned interengagement of the injection element and the control element and reestablishment of said aligned position after separation of the housings. The housings may, also, be spot-welded at selected points beyond break-away zones so that, upon breaking away of the spot welds, they can be separated, with subsequent re-alignment based on the break-away zones.
