Abstract
A plurality of mechanically coupled secondarily controlled hydrostatic machines with variable volume are connected to a line with impressed system pressure fed by a primary unit. By reducing the variable volume to 0 in individual hydrostatic machines the remaining machines are subjected to a higher torque which results in a greater pivot angle of the remaining secondary units. As a result the efficiency and controllability are improved. The changeover is effected in dependence upon an upper and lower switching point corresponding to the pivot angle of the unit remaining in engagement.
