摘要： A fuel injection pump in which the injection onset is varied by means of an injection adjuster, which has a two part adjusting piston acted upon by a hydraulic control pressure, which piston is adjustable counter to a restoring spring and by means of a bolt, engages the cam drive of the fuel injection pump in order to adjust the injection onset. To reduce the highest pressure in the high-pressure chamber of the fuel injection pump and to form the course of injection pressure, the adjusting piston is embodied in two parts, with a first piston that is adjustable relative to the second piston counter to a compression spring and the second piston is connected with the bolt. This makes possible a deflection motion of the piston relative to the second piston and a reduction in the pump piston stroke speed.

摘要： The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.

摘要： A fuel injection pump having a hydraulic injection onset adjustment apparatus is proposed in which a supplementary variation of the injection onset is obtained by means of the variation of the pressure deviating from proportionality. The pressure control valve used has a throttle connection between the pressure chamber and the spring chamber. The variation of the pressure is obtained by means of controlling the discharge channel of the spring chamber, by means of a control slide exposed to the pump pressure, whose restoring spring is variable in accordance with engine characteristics.

摘要： A distributor type fuel injection pump has a rotary magnet regulator (15) to actuate a control member (14) determining the fuel injection quantity, which rotary magnet regulator (15) is driven by a regulating signal produced in dependence on the operational parameters of the internal combustion engine. The rotary magnet regulator (15) is accommodated in a chamber (16) forming part of the pump housing (17) and filled with fuel. A damping device (25) is provided for the purpose of avoiding rotary oscillations of the rotating armature (20) in the rotary magnet regulator (15), which damping device (25) consist of a paddle (26) fixed firmly to the rotating armature (20) and of two separating walls (27,28) provided in the chamber (16). The paddle (26) extends radially from the rotating armature (20) and nearly fills the entire clear cross-section of the chamber (16) available for the swing movement of the paddle. The separating walls (27,28) separate a chamber section (161) comprising the entire range of swing of the paddle (26) from the remaining chamber section (162), whereby however throttle openings ensure a flow of fuel between the chamber section (161) and the chamber section (162) (FIG. 2).

摘要： A fuel injection pump for internal combustion engines having an electromagnetic final control element, which in order to adjust the end or onset of injection engages a control slide, located in the pump interior. Via a control shaft, the final control element chamber is hermetically sealed off from the pump interior in order to keep water contained in the fuel from reaching current-carrying parts of the final control element. As a result, fluid communication exists only via the bearing gap of the slide bearing of the control shaft and the bearing gap functions as a throttle. The throttle forms a water separator, which further reduces the concentration of water in the already small quantity of fuel reaching the final control element chamber through the throttle.

摘要： 1. Disk player with a magazine2.1. A known compact-disk player with a magazine consisting of several superimposed compartments for accommodating compact disks has a system of levers and a pulley driven by an electric motor in each compartment for removing a disk from the compartment.2.2. To decrease the considerable expense for each compartment (2) in the magazine (11), there is an access opening (15) on the rear wall of each compartment, through which a plunger (4) can travel to thrust the compact disk (7) out of the compartment. The plunger can be a flexible shaft that extends forward from the rear wall of the magazine through a tubular guide (3) and along one side of the magazine. The plunger can be introduced into and extracted from the compartment by means of a toothed rack (14) secured to the front of the flexible plunger (4) in conjunction with the cogwheel (10) that is driven by an electric motor (6) and engages the rack.2.3. When embodied in a compact-disk player the invention is especially appropriate for installation in a motor vehicle.2.3. Figures 1 and 2.
