Oscillations caused by solid friction in a hydraulic driving system of the previous report are dealt theoretically with the case where the critical value of static friction is different from the value of kinetic friction without slipping. The system consists of a table lying on a rectilinear sliding surface, an actuater cylinder, a 4-way servovalve, a releaf valve and an oil pump. In a similar way, the friction -velocity characteristic function is assumed to be given by a polygon having two straight line segments. The stick-slip motions of the sliding table are analysed considering the 4-way valve pressure-flow characteristic, friction-velocity relation, oil compressibility and the sizes of the hydraulic driving elements. Several types of limit cycles and the regions which they occur are shown in figures according to the parameters mentioned above.
