A rotational body supported in a housing of the apparatus carries an angle indication marker, which serves as a signal trigger of a signal transducer secured in a positionally fixed manner relative to the housing of the rotational body. The signal transducer has a transducer body axially displaceably disposed in its transducer housing. This body is displaceable in the direction of its longitudinal axis in order to actuate a first contact switch, and is provided inside its other end face with a switch contact, cooperating with the angle indication marker, of a second contact switch. After the actuation of both contact switches, the angle indication marker is located in a predetermined rotary position, which is indicated in the associated test circuit and serves in particular to ascertain the supply onset position of the drive shaft of a fuel injection pump for internal combustion engines.

A centrigural rpm governor for fuel injected internal combustion engines is proposed in which an adaptor assembly located inside the governor can be used over the entire range of practical applications of such a governor. The governor includes parallel coextensive arms, a governor lever and a cooperative governor rod which has a counterstop provided with a sliding block that is movably disposed between the parallel coextensive arms against the initial stressing force of a spring member with the counterstop being arranged to cooperate with a stop means pivotally associated with the housing. The spring member is arranged to load the sliding block and adjustable for the purpose of varying the initial stress and setting the onset of adjustment.

To optimize recording current flow, either for maximum signal output or for best linearity of a changing input signal with respect to output voltage, and provide for automatic optimization of the recording signal level, a ramp or sawtooth wave generator is connected to a recording head, the recorded signal is immediately read and differentiated and the differentiated signal is level detected, for example for zero level for maximum output voltage or for a predetermined level before substantial change of the differentiated signal has resulted, thus providing for optimum linearity, the optimum signal level--as desired--being stored in a memory and used to control the excitation current for subsequent excitation of the transducer heads by a data source.

A pneumatic diaphragm control member is proposed for a fuel injection device for internal combustion engines, especially for a boost-pressure dependent full-load stop, wherein the initial and end positions of a push rod provided with a control diaphragm and movable against a resetting spring can be varied, and wherein the effective pressure range is variable by means of separate adjusting means which do not affect one another. The push rod of the diaphragm control member contacts, in the unpressurized starting position, a stop screw mounted in the lid cover, and, in the pressurized end position, is in contact, by means of a counter stop attached to an extension of the push rod and adjustable in the direction of motion of the push rod, with a second end stop arranged in the pressure chamber. Thus, the bias of the resetting spring can be changed by changing the position of a bearing bushing for the push rod, which bushing serves as an abutment.
