Abstract
A hydraulic apparatus and a method of operating the hydraulic apparatus are disclosed. The hydraulic apparatus includes a flow control module, a first pump fluidly coupled to the flow control module via a first conduit, a first rotating group fluidly coupled to the flow control module via a second conduit, a first actuator fluidly coupled to the flow control module, a second actuator fluidly coupled to a second pump, a first accumulator, and a controller operatively coupled to the flow control module, the first charge valve, and the discharge valve. The first rotating group is configured to perform a pumping function and a motor function. The first accumulator is in selective fluid communication with the first actuator via a third conduit and a first charge valve, the second actuator via a fourth conduit and the first charge valve, and the first rotating group via a discharge valve.
