Abstract

A hydraulic system (50) includes a hydraulic actuator (30) , a pump (54) configured to supply fluid to the hydraulic actuator (30), and a first accumulator (72) fluidly connected to the hydraulic actuator (30). The first accumulator (72) is configured to store fluid received from the hydraulic actuator (30). The hydraulic system (50) also includes a motor (84, 184 ,284) drivingly connected to the pump (54) and fluidly connected to the first accumulator (72). The motor (84 ,184 , 284) is configured to receive the stored fluid from the first accumulator (72) to drive the pump (54). The hydraulic system (50) further includes a first discharge valve (78) fluidly connected between the first accumulator (72) and the hydraulic actuator (30). The first discharge valve (78) is configured to supply the stored fluid from the first accumulator (72) to the hydraulic actuator (30) without the stored fluid from the first accumulator (72) circulating through the pump (54).
