Abstract: A flow amplifier (1) with an inlet (4) and an outlet (5) is provided, between which a first branch (6), through which a flow of a fluid to be amplified is flowing, with a first throttling device (8), the throttle resistance of which is adjusted in dependence on the pressure across and by the flow rate through the first throttling device, and a second branch (7) with a second throttling device (11), the throttle resistance of which is adjusted in dependence on the throttle resistance of the first throttling device. In a flow amplifier of that kind, the amplification factor is intended to be made independently of pressure losses in the generation of the flow to be amplified. For that purpose, at least one pressure-divider (14, 15; 17, 18) with a central take-off point (16; 19) is provided, which is supplied by a pressure difference between inlet (4) and outlet (5), the pressure at the central take-off point (15, 19) controlling the flow rate through the second throttling device (11).

Abstract: A hydraulic function-performing unit is described, having a main housing (2) and at least one movable function-performing element (5, 9), the position and/or movement of which in the main housing (2) determines flow and/or pressure conditions and/or chamber volumes for hydraulic fluid, and having at least one sensor (21-25, 31-36). It is desirable for the construction of such a function-performing unit to be simplified. To that end, the sensor (21-25, 31-36) is accommodated inside a sensor housing (3). The sensor housing (3) and the main housing (2) have adjoining interface faces (4) and there is provided a transmission channel (26-30, 37-39) which is led through the interface face (4) and connects a measuring point in the main housing (2) to the sensor.

Abstract: A hydraulic steering arrangement for vehicles is proposed, with a steering motor (5), a flow amplifier (4) in fluid connection therewith, which amplifies a fluid flow measured by a steering measuring device (1), at least one sensor (10, 11, 13), which determines a performance characteristic of the vehicle, and a control device (9), which changes the amount of fluid supplied to the steering motor in dependence on an output signal of the sensor. In a steering arrangement of that kind, it is intended to correct or adapt the steering behaviour to the operational state of the vehicle using simple means. For that purpose, the control device (9) changes the amplification factor of the flow amplifier (4).
