Dual displacement is achieved by a variation of the shaft eccentric cam. The displacement control system is based on a hydraulic device, which actuates a hydraulic control valve mechanism to select minimum or maximum displacement. The dual displacement mode allows the motor to reduce the displacement down to 10% of the maximum, hence making the speed ten time higher.
