Abstract
A fast-displacement hydraulic pump is mechanically coupled to the engine drive shaft. A hydraulic motor is connected to the pump and to an accumulator by a first pipe. a tank is connected to the pump and to the accumulator by a second pipe. First actuators can be selectively operated to admit fluid to the two pipes. Second actuators can be selectively operated to block the fluid flow from the accumulator and the pump to the hydraulic motor, to couple the accumulator to the inlet port of the pump, and to couple the outlet port of the pump to the tank.
