Abstract: An electric servo steering arrangement and method for motor vehicles with a rotational angle sensor configuration for acquisition of the position of the steering movement has a support plate rotating relative or corresponding to the steering movement, with at least one code track and at least one stationary sensor acting on the code track. The code track is disposed about the rotational axis of the support plate and has markings for generating a sequentially changing bit pattern and the 360° of the circumference divided by the number of markings on the circumference defines a clock angle (?). The bit pattern is determined by a phase-shifted disposition of markings with respect to the fixed division of the clock angle (?).

Abstract: The invention relates to a steering servo for motor vehicles, with a drive unit arranged coaxially with the rack arrangement, which comprises a combination of a tubular electrical motor (9, 10, 12), with a recirculating-ball spindle drive. A particularly compact and cost-effective steering servo arrangement with few components is permitted, whereby the ball nut (7) of the recirculating-ball drive is mounted coincidentally with the rotor (9), which is arranged as an external rotor.

Abstract: An injection unit for an injection molding or die-casting machine comprises an injection ram which injects molten material out of an injection sleeve into a mold or die during a filling phase. This injection ram is connected to a drive piston which is movable within a drive cylinder for actuating the injection ram. The whole ram unit, comprising the injection ram and the drive piston, consists of at least two parts releasably connected together. A control device for the movement of the injection ram during the different phases of injection comprises a control valve. A signal transfer arrangement is interconnected between this control valve and the ram unit which is provided with a damping arrangement so that its releasably connected parts are movable relative to each other.
