摘要： In a distributor-type fuel injection pump there is a magnetic valve in the distributor, the valve component of which is fitted in an axial drilling in the distributor and is actuated by a magnet integral with the housing in order to interrupt the connection of a pump working chamber (14) of the distributor-type injection pump to a relief chamber during a given high-pressure injection phase. Owing to its design, a distributor (7) of such a fuel injection pump has a certain axial clearance in its bearing which affects the control travel of the valve member (39) in the distributor in relation to the fixed electromagnet (66). To prevent changes in the magnetic properties which could occur owing to this axial arrangement, a part of the magnetic circuit in the form of a magnet plate (55) can be moved together with the distributor so that the relative position between an armature (52) fixed to the valve member (39) and this part of the magnet core with which it forms a working air gap (80) does not change depending on the axial position of the distributor and thus the magnetic properties of the electromagnetic valve are maintained regardless of the axial position of the distributor.

摘要： The invention concerns a soft magnetic material which, in addition to iron and cobalt, contains at least one further alloy additive in order to obtain high saturation induction with at the same time high resistivity and good machinability. This is attained by an addition of cobalt which is reduced with respect to known alloys to between 5 and 20 mass %, with the simultaneous addition of an aluminium alloy component and preferably other, manganese or vanadium alloy components.

摘要： The invention concerns a fuel-injection pump of the distrubutor type with at least one piston (17) driven to execute a reciprocating action, a rotating distributor shaft (11) with a fuel-distribution bore (19) which, as the shaft rotates, connects the injection nozzle and the space (18) swept by the piston (17), plus a control valve (25) which meters the fuel to be injected. In order to ensure highly stable hydraulic flow on opening and closing the control valve (25), a low-pressure piston (43) is connected to the obturator element (35) of the control valve (25), the low-pressure piston being mounted so that is moves in the longitudinal direction inside a section (26) of the wall lying on the low-pressure side of the control valve (25) behind the outlet aperture of a relief bore (27). The external diameter of the low-pressure piston (43) is preferably close to the diameter of the obturator element surface which presses against the valve seat (34).

摘要： In an electronic circuit arrangement for triggering exciter coils of electromagnetic components provided with auxiliary wiring, in particular free circulation wiring, preferably solenoid valves (MV1 to MVn), the components are connected in series to a controllable switching element (3) in order to obtain flexible control. To reduce the number of circuits, manufacturing costs and the space required, the connections (1, 4) of this series circuit lead directly to a collecting point (A, B, C), and the connections (2) between the components (MV1 to MVn) and the switching elements (3) also lead to these collecting points (A, B, C) via diodes (D1 to Dn). A single auxiliary circuit (TF, CL, 10, 11) common to all components is connected to these collecting points. The elements of the auxiliary circuit are therefore used in numerous ways, since they are available to all the electromagnetic components.

摘要： A process for controlling and detecting the movement of an armature of an electromagnetic switching device with an excitation coil comprises the following steps: to move the armature into an operating position, a current (i) or a voltage (u1) is applied to the excitation coil (3); before the armature starts moving, the current or the voltage is increased above a value at which the armature remains in the operating position; before the armature stops moving, the current or the voltage is decreased to a given value sufficient to maintain the armature in the operating position; finally, the variations in the current or the voltage with time are determined after the value used to detect the moment at which the armature stops moving has been adjusted. This process can be used, for example, to monitor the solenoid valve of a fuel injection device in an internal combustion engine with great precision, which permits optimal control of the time and duration of injection.

摘要： An electromagnet, especially for use in pilot valves for the direct control of the quantity of fuel injected in fuel injection pumps, has a pot magnet (25) of soft magnetic material, an annular exciting coil (30) and an armature (29) arranged in front of the pot magnet with a working air gap. To improve the dynamic behaviour of the electromagnet (20), i.e. to obtain extremely short switching times, with a simple technical construction of the magnetic circuit, the pot magnet (25) and/or armature (29) made as a solid component has an even number of at least four radial slots (41) passing through the pot magnet (25) or the armature (29) over its entire axial length. Successive radial slots (41a, 41b) extend alternately from the outer or inner surface (321 or 311) and terminate there, leaving a solid section of material (42 or 43).

摘要： The invention concerns a circuit arrangement and a process for operating an electromagnetic consumer (1) on a supply voltage (4), with a switching element connected in series to the consumer (1) and an energy-supply circuit (9) which accelerates the switching on of the consumer (1). The energy-supply circuit (9) contains a charging capacitor (CL) which can be charged in a defined manner by means of a controllable switching element (11) via an inductance (L) in order to accelerate the switching on process of the electromagnetic consumer (1) in a precisely controlled manner. Possibilities for accelerating not only the switching on process but also the switching off process of the electromagnetic consumer (1) are described.
