摘要： PURPOSE:To prevent noise generation without dropping the power transmitting efficiency by changing the oil pressure in a cylinder hole and a communication port in accordance with rotation of a cylinder block. CONSTITUTION:When a plunger 12 moves rotationally from the lower dead point in compliance with the rotation of a cylinder block 4, the oil chamber 13 to which a communication port 13a is leading remains out of communication to anywhere until the communication port 13a comes in mating with the discharge port 14, and the pressure of the working oil in the oil chamber 13 is boosted by movement of the plunger 12 in the compressive direction. When the plunger 12 is rotated from the upper dead point, the oil chamber 13 leading to the communication port 13a remains out of communication to anywhere until the communication port 13a comes into mating with the suction port 15, and the working oil in the oil chamber 13 is decompressed with movement of the plunger 12 in the expansive direction. Thereby generation of high frequency noise can be prevented without dropping the power transmitting efficiency.

摘要： PROBLEM TO BE SOLVED: To efficiently cool the rotor and stator of a motor, using a simple structure.
SOLUTION: A notch 20b that extends radially is formed at a plurality of steel plates 20 constituting a rotor core 21. The steel plates 20 are laminated by shifting phase by 90°, respectively, to constitute a cooling oil path 27 extending radially. So, the oil in the cooling oil path 27, which is supplied through the interior of a rotor shaft 18 is energized under centrifugal force to flow efficiently toward the outside in the radial direction, for improved cooling efficiency of the rotor and stator. Further, the rotor core 21 is not required for machining to provide a complex cooling oil path, resulting in the reduced number of processes and in the processing cost. Since a permanent magnet support hole 20b formed at the rotor core 21 communicates with the cooling oil path 27, the oil that flows the cooling oil path 27 cools the permanent magnet 22, supported in the permanent magnet supporting hole 20b, for cooling the rotor in further efficient manner.

摘要翻译：要解决的问题：使用简单的结构有效地冷却电动机的转子和定子。解决方案：径向延伸的凹口20b形成在构成转子芯21的多个钢板20上。钢板20分别通过相移90°层压，以构成径向延伸的冷却油路27 。因此，通过转子轴18的内部供给的冷却油路27中的油在离心力作用下被有效地向径向外侧流动，以提高转子和定子的冷却效率。此外，转子芯21不需要进行机械加工以提供复杂的冷却油路径，从而减少了工艺数量和加工成本。由于形成在转子铁心21的永久磁铁支撑孔20b与冷却油路27连通，所以流过冷却油路27的油冷却永久磁铁支承孔20b中的永久磁铁22，以冷却转子进一步有效的方式。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a hybrid vehicle drive, having superior handleability and productivity, capable of obtaining high space factor of a stator coil. SOLUTION: Each of power supply terminals 537 (537U, 537V, and 537W) is formed at respective positions. Each terminal 537 is guided to a terminal holder through bus bars 531 (531U, 531V and 531W) for supplying drive current to bus rings 532U, 532V and 532W. A plurality of Salient-like terminals 533U, 533V and 533W are respectively formed at inner peripheral ends of the rings 532U, 532V and 532W, and a plurality of salient-like terminals 534 are formed radial from outer peripheral ends of bus ring 530 for connecting the midpoint. An exposed surface of the rings 532, 530 except an essential portions of the terminals 533, 534 of the rings 532, 530 are covered uniformly with insulating resin. As the resin, a fluororesin is preferred in view not only of the function as insulating film, but also having low frictional coefficient and high film strength.

摘要： PURPOSE:To reduce the vibration exciting force applied to a swash plate, etc., and suppress increase of the rate of pulsation by reserving a larger gap than a communication port between a discharge port and a suction port formed in d distribution valve plate. CONSTITUTION:A gap larger than a communication port 13a is reserved between a discharge port 14 and a suction port 15 formed in a distribution valve plate 7. That is, the ports 14, 15 are arranged so that the communication port 13a contacts the suction port 15 and separates from the discharge port 4 when plunger is positioned at the lower dead points B.D.C..., and the communication port 13a contacts the discharge port 14 and is positioned apart from the suction port 15. Thereby the oil pressure change in cylinder can be made gradual, the vibration exciting force applied to a swash plate, etc., be reduced, and increase of the rate of pulsation be suppressed.
