    • According to a present powertrain, a first rotation shaft serving as an input shaft of a front side gear mechanism is located in a portion of a vehicle lower than a second rotation shaft serving as an output shaft, so that a crankshaft of an engine provided coaxially with the first rotation shaft is located in a portion of the vehicle lower than in a conventional example. Solely the engine shaving a heavy mass is thus disposed in a lower portion, so as to achieve a lower position of the center of gravity of the vehicle. In this manner, a powertrain having a layout structure attaining lower center of gravity as well as high rigidity of a body and improvement in aerodynamic characteristics is provided.

    • An air conditioner comprising a refrigerant forward path branching on a discharge side of a compressor in an outdoor unit, one of the branched portions being defined by connecting a first four-way valve, a first outdoor heat exchanger and a first outdoor expansion valve to one another in this order, and the other of the branched portions being defined by connecting a second four-way valve, a second outdoor heat exchanger and a second outdoor expansion valve in this order, the path extending to an indoor unit from the respective outdoor expansion valves through a liquid-side piping, and returning to the outdoor unit from the indoor unit through a gas-side piping to branch, one of the branched portions being connected to the first four-way valve via a check valve placed in communication in a forward direction and the other of the branched portions being connected to the second four-way valve, the air conditioner being controlled such that, when heating operation is switched to defrosting operation, the second four-way valve is switched if a pressure difference between discharge pressure and suction pressure of the compressor is equal to or above a predetermined value, and the first four-way valve is switched after a gas-side pressure of the second outdoor heat exchanger has risen, whereby the four-way valves are prevented from being made inoperative due to short-circuit between high pressure side and low pressure side.
    • 一种空气调节器,包括在室外机的压缩机的排出侧分支的制冷剂正向通路,其中一个分支部分通过将第一四通阀,第一室外热交换器和第一室外膨胀阀连接到一个 另一个是依次连接第二四通阀,第二室外热交换器和第二室外膨胀阀来限定的分支部分,从室外膨胀部分向室内机延伸的路径 阀通过液体侧管道,并且通过气体侧管道从室内单元返回到室外单元,其中一个分支部分经由与第一四通阀连接的止回阀连接到第一四通阀 前进方向和另一个分支部分连接到第二四通阀,空调被控制成使得当加热操作切换到除霜 如果压缩机的排出压力和吸入压力之间的压力差等于或高于预定值,则第二个四通阀被切换,并且第二个四通阀在第二个四通阀的气体侧压力之后切换 室外热交换器升高,由于四通阀由于高压侧和低压侧之间的短路而被阻止不起作用。
