    • The invention concerns a positioning drive which is used in particular for machine tools and which comprises a hydraulic motor (10). The hydraulic motor comprises: a control disc (17) which is rotatable with a motor shaft (18) and is provided with a radial cam (19); a control valve (12) which, with the hydraulic motor (10), forms a unit with a preferably multi-part housing (37, 46) and comprises a valve piston (15) which can be displaced between a plurality of settings; a control component (16) by means of which the valve piston (15) can be supported on the control disc (17); and an adjusting component (65) which is operatively disposed between the control component (16) and the valve piston (15) and is coaxial to the latter. The relative position between the valve piston (15) and control component (16) can be varied by the relative adjustment of the adjusting component (65) to the valve piston (15). The position of the adjusting component (65) relative to the valve piston (15) can be secured by a releasable securing component. In order to be able to adjust the position between the valve piston (15) and the control component (16) very simply, the outer of the two parts, valve piston (15) and adjusting component (65), is guided outwards through the housing and the securing component (72, 80) is accessible externally of the housing.

    • In a hydraulic system with a pump (1) and load (4, 104), a bleed valve (16) is provided, which is connected to the pump pressure side (3) and opens towards the tank (2) when a predetermined pressure difference between the pump pressure and maximum load pressure is exceeded. This bleed valve is used in addition to a pump control device (22), wherein provision is made for the pressure difference at the bleed valve (16) to be somewhat greater than the pressure difference preset at the pump control device (22). The control apparatus (20) can preset the pump delivery rate in dependence on setting signals (s1, s2) and regulate it in dependence on a difference pressure signal (U). In addition, it is possible to compare the pressure difference signal with a pressure difference limit and to throttle the control valves (6, 106) in dependence thereon, in order to prevent overloading. The transducer delivering the pressure difference signal can be a position sensor (18) at the bleed valve (16). As a result, the performance of the hydraulic system can be improved in a simple manner.
