PURPOSE: A hybrid-type machine is provided to operate the stepping down voltage in short time by composing a machine with low components. CONSTITUTION: A hybrid-type machine comprises an electrical storage device(120), a motor for stepping down voltage(300), a hydraulic motor for stepping down voltage(310), and a hydraulic circuit. The electrical storage device supplies power to an assist motor for an engine. The motor for stepping down voltage is reversely driven through the power of the condenser(19) of the electrical storage device. The hydraulic motor for stepping down voltage is connected to the motor for stepping down voltage. The hydraulic circuit comprises a circulation circuit and a conversion valve(330) and is connected to the hydraulic pressure supply port and hydraulic pressure discharge port of the hydraulic motor for stepping down voltage. The conversion valve connects the hydraulic motor for stepping down voltage to the hydraulic circuit selectively. |
