Method for energy recovery of hydraulic motor

An energy recovery system for a reversible hydraulic motor system, the energy recovery system comprising:

• a pump to pressurize fluid;
• a hydraulic motor to receive the pressurized fluid from the pump to rotate in a first direction;
• an accumulator in selective fluid communication with the hydraulic motor and the pump, the accumulator configured to store pressurized fluid;
• a valve structured and arranged to facilitate the storage and discharge of stored pressurized fluid of the accumulator;
• and
• a controller coupled to the valve and, and during a reverse motor command, configured to:
• pivot a swashplate of the hydraulic motor over a center position when rotation of the hydraulic motor is in the first direction;
• position the valve to a position to facilitate storage of the pressurized fluid into the accumulator;
• position the valve to a position to facilitate discharge of the stored pressurized fluid of the accumulator to the hydraulic motor as the hydraulic motor begins to rotate in an opposite, second direction;
• and
• position the valve to a block position to inhibit flow of the pressurized fluid into or out of the accumulator.
