Abstract: The invention concerns a frequency converter (15) for an electromotor (14) with an intermediary circuit (3, 4, 6, 7), in which a braking circuit (8, 9, 10) with a switch (8) and a load (10) is arranged. With such a frequency converter, it is possible to ease the demands on protection measures, even though the load (10) is placed outside the frequency converter (15). For this purpose, the load (10) is galvanically separated from the intermediary circuit (6, 7).

Abstract: A hydraulic steering device (1), in particular for vehicles, is disclosed, having a housing in which two sliders are arranged to move relative to one another and together form at least one adjustable throttle (A1-A6, Ad), a restoring device for restoring the two sliders to their neutral position being provided, one of the two sliders being driveable and the other of the two sliders being in operative connection with a measuring device (7). In such a steering device it is desirable to improve the correlation between steering torque and flow amplification; in particular it is desirable to linearize the relationship better. For that purpose the measuring device (7) is arranged in a flow path (8) closed in itself, and operates as a pump, whilst an open flow path (9) runs past the closed flow path (8) from an inlet connection arrangement (P, T) to an outlet connection arrangement (A, B).
