摘要： Fuel injection pump in which the piston is driven via a rocker (6) bearing a roller (14) running on a cam (20) and thus providing the rocking motion to drive the piston via the rocker. Here, the roller (14) is borne in a shell-like recess (12) in one of the rocker arms (10) so that the entire outer surface of the roller supports the rocker (6) as it rotates.

摘要： A fuel injection device for internal combustion engines, having a fuel injection pump, which can be inserted into a housing of the engine and is axially clamped together with a fuel injection valve by means of a clamping sleeve. The valve, with an end remote from the pump, protrudes into a combustion chamber of the engine. A fuel supply line to the fuel injection pump feeds into an annular chamber encompassing the clamping sleeve and, via through openings in the clamping sleeve and inlet conduits in the pump housing, the valve can be connected to a pump working chamber of fuel injection pump. According to the invention, the fuel filter in the inlet to the pump working chamber is constituted by the clamping sleeve, which has a multitude of filter openings for this purpose in its circumference wall, in the vicinity of the annular chamber.

摘要： PCT No. PCT/DE94/00693 Sec. 371 Date Mar. 1, 1995 Sec. 102(e) Date Mar. 1, 1995 PCT Filed Jun. 18, 1994 PCT Pub. No. WO95/02123 PCT Pub. Date Jan. 19, 1995A fuel injection device with a pump plunger which is driven in reciprocation and a working space which is enclosed by the pump plunger, and is connected to an injection valve connected directly to the pump housing. To control the fuel injection quantity and the injection instant, a solenoid valve is provided which is arranged in a fuel passage that is connected to the pump working space and serves for the filling and/or relief of the pump working space. To reduce the volumes subjected to the high pressure, the fuel passage is arranged in such a way that the fuel passage intersects the cylinder bore which accommodates the pump working space, and the solenoid valve is arranged at the entry of this passage.

摘要： A cylinder head cover of an internal combustion engine with a solenoid-controlled injection device using pump-nozzle units designed so that the solenoid valves are supplied with power in a manner that is advantageous from the manufacturing point of view and provides reliable operation. For this purpose, the cylinder head cover covers the entire injection device and contact elements designed as inserts are injected into the cylinder head cover made of plastic in an injection molding process. The contact elements automatically come into a close-fitting contact with contact surfaces mounted on the outside of the solenoid valves when the cylinder head cover is mounted on a cylinder head. The contact elements are combined with contact segments in a central connector mounted on the outside of the cylinder head cover, wherein the power is supplied for the solenoid valves centrally from a controller.

摘要： A fuel injection valve for internal combustion engines, having an axially movable valve member which, with its end oriented toward the combustion chamber, opens and closes a through flow cross section to at least one injection opening and which, with its end remote from the combustion chamber, protrudes into a fuel-filled spring chamber in which a valve spring is clamped, which acts on the valve member in the closing direction and is supported with its end remote from the valve member against a deflecting piston which, during the supply of high pressure fuel to the fuel injection valve, can be moved a certain distance into the spring chamber and thereby increases the initial stress force of the valve spring, and having a connecting conduit between the spring chamber and a low pressure fuel chamber. The connecting conduit between the spring chamber and the low pressure fuel chamber is embodied as a throttle bore in order to increase the injection opening pressure.

摘要： The invention relates to a fuel injection valve for internal combustion engines. Said valve has a valve member (21) which can be axially displaced and which controls, with the end situated on the side of the combustion chamber, the effective area of flow to at least one injection opening (27) by increasing or decreasing said area. The valve projects, with the end situated at a distance from the combustion chamber, into a fuel-filled spring chamber (37). A valve spring (41) which impinges upon the valve member (21) in the direction of closure is loaded in said spring chamber. Said valve spring, with the ends thereof facing away from the valve member, rests on a pressure relief piston (45). Said pressure relief piston can be displaced along a determined path into the spring chamber (37) when the fuel is supplied to the fuel injection valve under high pressure, thereby increasing the prestressing force of the valve spring (41). The fuel injection valve also has a connecting channel between the spring chamber (37) and a fuel low-pressure chamber (73). The connecting channel is configured as a throttling port (99) between the spring chamber (37) and the fuel low-pressure chamber (73) in order to increase the pressure at the injection opening.
