摘要： A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

摘要： In a process and an apparatus for determining the coercive field strength and the maximum pitch of the hysteresis cure in set-up techniques a test body is magnetized in a magnetic field of an exciter coil fed with an alternating current, as the hysteresis curve of the test body is traversed a number of times with the frequency of the alternating current and the tangential field strength on the test body surface generated by the exciter coil is detected continuously with the aid of a magnetic field strength sensor during the traversing of the hysteresis curve. From a harmonic analysis of the time course of the tangential field strength within one period there is calculated a distortion factor for the determination of the maximum pitch of the hysteresis curve. The coercive field strength is ascertained by the means that the point of time of the first zero passage of the harmonic signal after the zero passage of the tangential field strength signal is sought and the amplitude of the tangential field strength signal present at this point of time is regarded as measure for the coercive field strength.
