Abstract
A hydraulic system, working vehicle, and method for producing hydraulic power to a hydraulic system of a working vehicle is provided. The hydraulic system includes a fixed displacement hydraulic pump and a speed and torque controlled electric motor for driving the hydraulic pump. An electric controller is arranged to adjust the speed of the electric motor and to thereby adjust produced hydraulic fluid flow and pressure in the system. Further, there is a bypass flow channel including a throttle element for directing limited continuous discharge fluid flow from the system.
