Abstract:
A regeneration method for a hydraulic system having a first actuator and a hydraulic power converting device, said regeneration method comprising the steps of:draining hydraulic fluid under pressure from the actuator; sensing pressure of the hydraulic fluid drained from the actuator to produce an indication of a first pressure; sensing pressure of hydraulic fluid at an inlet of the hydraulic power converting device to produce an indication of a second pressure; determining when the fist pressure is greater than the second pressure; and in response to making the determination and when a flow rate of fluid from the actuator is a predefined amount greater than a flow rate desired for fluid supplied to the hydraulic power converting device, selectively routing the hydraulic fluid drained from the actuator to the inlet of the hydraulic power converting device thereby driving the hydraulic power converting device.
