Abstract

Controller and positioner is for machine tool magazines, workpiece carriers or machine parts, and has a press, medium pump, a hydraulic motor to drive the magazine with a control valve in its outlet duct, a switching disc with position grooves, rotatably fastened to the working spindle of the magazine, and a control piston in the valve housing and moving by the medium to form a variable throttle with a control edge in the motor outlet. The throttle is adjusted by a fixing bolt connected to the piston after the bolt has been set on the switching disc, by inclined surfaces. A bypass has a constant throttle and leads from the hydrostat outlet duct to the control valve. There is a valve in an oil circuit independent of the motor which is acted on by a further control valve.
