摘要： A housing of an axial piston device is provided with a drain port for discharging the retained oil to the outside and a supply oil passage for guiding lubricating oil, which has been supplied from an oil source, toward a first hydraulic axial piston member. The drain port is arranged so as to bring about such a retained-oil level that a second hydraulic axial piston member, which is disposed below the first hydraulic axial piston member, is partially or entirely immersed in the retained oil while the first hydraulic axial piston member is not immersed in the retained oil.

摘要： In a hydrostatic transmission (HST), a lubricating fluid passage is formed in an input shaft and has a pair of radially opposite lubricating fluid spill ports open at an outer peripheral surface of the input shaft. Both of the radially opposite lubricating fluid spill ports face a lubricated object of the HST. The lubricating fluid passage includes an axial fluid passage and a pair of radial fluid passages that are extended radially from the axial fluid passage to the outer peripheral surface of the input shaft so as to be radially opposite each other. Open ends of the respective radial fluid passages at the outer peripheral surface of the input shaft serve as the respective radially opposite lubricating fluid spill ports.
摘要翻译： 在静液压传动装置（HST）中，在输入轴上形成润滑流体通道，并且在输入轴的外周面上具有一对径向相对的润滑流体溢出口。 两个径向相对的润滑流体溢出口均面向HST的润滑物体。 润滑流体通道包括轴向流体通道和一对径向流体通道，其从轴向流体通道径向延伸到输入轴的外周表面，以便彼此径向相对。 在输入轴的外周表面处的相应的径向流体通道的开口端部用作相应的径向相对的润滑流体溢出口。
