摘要： An electric motor-driven compressor is positioned closer to the center of gravity of an engine than a compression mechanism, and is mounted in such a manner that an axial direction of an electric motor is parallel to a crank shaft of the engine. Therefore, a vibration force produced by the engine and applied to the electric motor is reduced.

摘要： Refrigerant passages in a compressor include an upper refrigerant passage and a lower refrigerant passage. The upper refrigerant passage is positioned above a datum line extending through a center of a rotor shaft of a compressor motor and perpendicularly to the rotor shaft, and the lower refrigerant passage is positioned below the datum line. A cross-sectional area of the upper refrigerant passage is larger than that of the lower refrigerant passage. Thus, even when lubricating-oil blocks the lower refrigerant passage, the refrigerant flows through the upper refrigerant passage, thereby reducing the pressure loss of the refrigerant, and preventing the lubricating oil from being caught in the refrigerant and discharged with the refrigerant from the compressor.
摘要翻译：压缩机中的制冷剂通道包括上制冷剂通道和下制冷剂通道。上部制冷剂通道位于延伸通过压缩机电动机的转子轴的中心并垂直于转子轴的基准线上方，下部制冷剂通道位于基准线下方。上部制冷剂通路的截面积大于下部制冷剂通路的横截面积。因此，即使润滑油阻挡下部制冷剂通路，制冷剂流过上部制冷剂通路，从而降低制冷剂的压力损失，并且防止润滑油被夹在制冷剂中并与来自压缩机的制冷剂一起排出。

摘要： A first lubricating oil passage and a second lubricating oil passage, extended from a contacting surface between a partition wall and a fixed scroll are formed in the partition wall (middle housing). A recess for communicating the first lubricating oil passage with the second lubricating oil passage is formed on the fixed scroll. Accordingly, the lubricating oil amount between the first lubricating oil passage and the second lubricating oil passage is easily controlled by adjusting the size of the recess.

摘要： Lubricant oil, separated from compressed fluid and stored in an oil storage chamber formed beneath a motor, is introduced via an internal oil supply passage to an attachment groove formed for installing a main bearing. The lubricant oil passes through the main bearing, and flows toward a compressor. The lubricant oil is also supplied to an oil supply hole formed inside a rotation shaft of the motor via lubricant oil grooves, and lubricates and cools a needle bearing. Accordingly, axial length of housing protruding portion is reduced, and thereby reducing an entire axial length of the electrically-driven compressor apparatus.

摘要： A scroll compressor having injection ports 70A and 70B opened to operating chambers Vc during a predetermined period of a complete compression cycle, so that a part of the refrigerant circulating in a refrigerating system is injected into the compression chambers from the injection ports. The injection ports are opened to an intermediate pressure chamber, which is at a pressure between the pressure of the refrigerant sucked into the compressor and the pressure of the refrigerant discharged from the compressor. The intermediate pressure chamber is arranged so as to eliminate pressure pulsations therein. Check valves 72A and 72B are provided in an end plate 54 of a stationary scroll member 50. Furthermore, relief valves may also be provided in the end plate for releasing the pressure of the operating chambers to a low pressure side of the refrigerating system.

摘要： A swash plate type compressor has a rotary shaft, an inclined swash plate for rotation with the shaft, and a plurality of pistons connected to the swash plate. Each piston defines at both ends thereof a pair of working chambers. The piston reciprocates while being subjected to a swing motion concomitant with the rotation of the swash plate, to suck a fluid into the working chambers for compression. The swash plate is mounted on the shaft through a support unit which serves to selectively vary the inclination of the swash plate and shift the center of rotation of the swash plate along the shaft. The fluid is introduced from a suction passage through and around the swash plate to suction chambers formed adjacent the working chambers. A bypass passage is formed to directly communicate the suction passage with the suction chamber on one side of the shaft while bypassing the swash plate. When the inclination of the swash plate is decreased and the rotational center position thereof is shifted so that substantially no compression of fluid is completed in the working chambers on the one side of the shaft to decrease the displacement of the compressor, the fluid flows in the one side suction chamber through the bypass passage responsively to the flow of fluid toward another side working chambers to lubricate and cool sliding parts for the shaft.
摘要翻译：斜盘式压缩机具有旋转轴，用于与轴一起旋转的倾斜斜盘和连接到斜盘的多个活塞。每个活塞在其两端限定一对工作室。活塞在与旋转斜盘的旋转同时进行摆动运动的同时往复运动，将流体吸入工作室进行压缩。旋转斜盘通过支撑单元安装在轴上，支撑单元用于选择性地改变斜盘的倾斜度并沿着轴移动斜盘的旋转中心。流体从吸入通道通过旋转斜盘周围引入到邻近工作室形成的吸入室。旁路通道形成为在旁路旋转斜盘时将抽吸通道与轴的一侧上的吸入室直接连通。当斜盘的倾斜减小并且其旋转中心位置移动时，使得在轴的一侧的工作室中基本上没有完成流体的压缩以减小压缩机的位移，则流体在一侧抽吸室通过旁路通道，响应于流体流向另一侧工作室，以润滑和冷却用于轴的滑动部件。

摘要： A refrigerant passage within a main shaft includes an axial refrigerant passage extending in parallel with the main shaft from the end surface thereof, and a radial refrigerant passage communicating with the axial refrigerant passage and extending radially outwardly. The radial refrigerant passage is located between the end surface of the main shaft and a motor rotor. Thus, when the main shaft rotates, suctioned refrigerant is uniformly sprayed toward an entire coil. Further, the refrigerant flows toward a compression mechanism through the electric motor, thereby cooling the electric motor effectively.
