  • Patent number: 4597610
    Abstract: A load-dependent brake force governor is proposed, in which the actuation linkage which influences the governor valve is additionally used for the purpose of actuating a signal transducer which then produces a load-dependent signal. The signal transducer can be either a control valve (FIG. 1) or an inductive transducer (FIG. 2). In this manner, even when the brake is not actuated, a load-dependent signal is available for use, with which further devices, such as an engine brake or a retarder, an axle load indicator or a headlight range control means, can be actuated. A supplementary pickup of the movement of the vehicle chassis can be omitted. The brake force governor is preferably applicable to motor vehicles.

  • Patent number: 4594984
    Abstract: A regulating device is proposed for the mixture composition of an internal combustion engine having a signal sensor and having regulating ranges which can be switched over between lambda equals one and the lean range. The lambda-equal-to-one regulation is effected by means of a two-point regulator and the lean regulation is effected either via an altered set-point value of the two-point regulator or with the aid of a steady regulator. The transitions between the two types of regulation take a course dependent on a selectable function, in order to avoid abrupt changes in rpm. A switchover is also made to controlled operation for a brief period at the beginning of each type of regulation.

  • Patent number: 4589706
    Abstract: A vehicle brake system including a brake force booster, controllable a brake pedal, for actuating a main brake cylinder in order to supply wheel brake cylinders with braking pressure for service braking operations and also includes brake pressure control valves, which direct braking pressures into individual wheel brake cylinders if there is a danger that the wheels will lock during braking. To this end, pressure is supplied to the brake pressure control valves from the brake force booster via controlled valves. In order to be able to reduce drive slip as well, the controlled valves are embodied as a switchover valve, so that pressure can be directed to the brake pressure control valves directly from a pressure supply container bypassing the brake force booster. The vehicle brake system is inexpensively further embodied for reducing drive slip by modifying the control valves.

  • Patent number: 4589391
    Abstract: A device is proposed for controlling the injection start to a set-point value dependent on operating parameters, in which the period of time between the appearance of an injection start signal and a reference marking (for instance, a top-dead-center signal) is counted out and the result of counting is compared with the set-point value. To avoid malfunctioning, the triggering of the counting process is possible in only one, predetermined crankshaft angle range. Various values are provided for the counting-out frequency. In the exemplary embodiment they are within the range between 50 and 200 kHz. In case of failure, a control of injection onset is effected, and as needed, a limitation of the fuel quantity as well--for instance to 70% of the respectively determined quantity.

  • Patent number: 4587844
    Abstract: A temperature-dependent measuring resistor layer is applied to a first carrier, the temperature and/or resistance of which layer is regulated in accordance with the mass of the medium. The first carrier is approximately rectangular and in particular is disposed parallel to the flow direction in a convergent section of the flow cross section. In a parallel section of the flow cross section, a second carrier having a compensating resistor is disposed, which likewise has a rectangular cross section and in particular extends parallel to the flow direction. An arrangement of this kind not only avoids deposits on the end face of the first carrier pointing into the flow but also prevents the result of measurement at the measuring resistor layer from being affected by the position of the second carrier in the flow cross section.

  • Patent number: 4586470
    Abstract: A centrifugal speed governor, functioning as a minimum-maximum-speed governor, includes an adjusting member which is pivotable for adjusting the supply quantity, and the governor rod of the associated injection pump is adjustable via an intermediate lever by means of the adjusting member and a governor spring which is displaceable counter to the force of associated governor springs. The travel of the governor rod is limited in the direction of an increasing supply quantity by a governor rod stop including a starting spring. With the adjusting member resting on an end stop, the governor rod is pressed away from a basic test position (P) into its full-load position (V), and the differential travel (.DELTA.R) thereby resulting is absorbed by an accumulator in the governor linkage, preferably in the governor sleeve. The deflection stroke (A) of the accumulator is only slightly longer than that required to compensate for the differential travel (.DELTA.R).

  • Patent number: 4585174
    Abstract: An electro-magnetically operable valve serving especially as fuel injection valve for a fuel injection device of internal combustion engines. The valve is composed of a valve housing, in which a magnetic coil is disposed around a core. The core has a concavely formed stop face against which, during excitation of the magnetic coil, a ball rests. The ball serves as an armature and movable valve part and cooperates with a fixed valve seat. The radius (r.sub.1) of the concavely formed stop face of the core is larger by about 0.1 to 1 mm than the radius (r.sub.2) of the ball. This causes a sufficient hydraulic cushion between the end face of the core and the ball when the ball is attracted toward the core upon magnetic energization of the latter and thus prevents a bouncing movement of the ball or its sticking to the core, when the ball is biased toward the valve seat upon de-energization of the core.
