    • The present invention is directed to a power transmission apparatus for a power driven lawn mower. The lawn mower has a housing, an engine mounted on the housing, a moving blade coupled to the engine and wheels which are swingably mounted on the housing. The swinging of the wheels moves the housing towards and way from the ground in order to raise and lower the housing to thereby raise and lower the lawn mower blade. The power transmission apparatus comprises a transmission mechanism and a transmission chamber for housing the transmission mchanism, the chamber including a guide structure. The transmission mechanism includes a drive shaft coupled to the engine and a single reduction gear mechanism coupled to the drive shaft and the wheels for transmitting the rotation of the drive shaft to the wheels. The reduction gear mechanism includes an engaging structure for engaging the guide structure in the chamber wherein the swinging movement of the wheels causes a corresponding movement of the reduction gear mechanism. The corresponding movement of the reduction gear mechanism is guided by the movement of the engaging structure in the guide structure.
    • 本发明涉及一种动力驱动割草机的动力传递装置。 割草机具有壳体,安装在壳体上的发动机,联接到发动机的可动叶片和可摆动地安装在壳体上的轮子。 轮的摆动使壳体朝向和离开地面移动,以便升高和降低壳体,从而升高和降低割草机叶片。 动力传递装置包括传动机构和用于容纳传动机构的传动室,所述腔室包括引导结构。 传动机构包括联接到发动机的驱动轴和联接到驱动轴和车轮的单个减速齿轮机构,用于将驱动轴的旋转传递到车轮。 减速齿轮机构包括用于接合腔室中的引导结构的接合结构,其中车轮的摆动运动引起减速机构的相应运动。 减速齿轮机构的相应运动由接合结构在导向结构中的运动引导。

    • A fuel cell stack includes a first separator and a second separator. A reactant air flow channel is formed on one surface of the second separator. A fuel gas flow channel is formed on one surface of the first separator. Further, a coolant air flow channel is formed on the first separator, on the other surface opposite to the fuel gas flow channel. The reactant air flow channel is connected between a reactant air inlet and a reactant air outlet. A coolant air flow channel is connected between a coolant air inlet and a coolant air outlet. The reactant air flow channel and the coolant air flow channel are configured such that the pressure loss of the reactant air between the reactant air inlet and the reactant air outlet and the pressure loss of the coolant air between the coolant air inlet and the coolant air outlet are substantially the same.
    • 燃料电池堆包括第一分离器和第二分离器。 反应物气流通道形成在第二分离器的一个表面上。 燃料气体流路形成在第一分离器的一个表面上。 此外,在第一分离器上,在与燃料气体流动通道相对的另一个表面上形成冷却剂空气流动通道。 反应物气流通道连接在反应物空气入口和反应物空气出口之间。 冷却剂空气流动通道连接在冷却剂空气入口和冷却剂空气出口之间。 反应物空气流动通道和冷却剂空气流动通道构造成使得反应物空气入口和反应物空气出口之间的反应物空气的压力损失与冷却剂空气入口与冷却剂空气出口之间的冷却剂空气的压力损失 基本相同。
