    摘要： The present invention prevents the clogging of an oil supply hole in a compressor due to foreign substances, such as sludge, and avoids performance degradation caused by leakage of discharged refrigerant. In a compressor that is configured to guide lubricating oil separated from the discharged refrigerant by an oil separator to a radial bearing 10 supporting a drive shaft 8, through a oil supply hole 29, a rotating member 30 that rotates together with the drive shaft 8 is provided adjacent to the radial bearing 10 on the drive shaft 8, and lubricating oil is supplied to the radial bearing 10 via a gap between the external surface of the rotating member 30 and the internal surface of a circular hole 31 that supports the rotating member 30. An oil transport groove 32, which alternately communicates with the outlet of the oil supply hole 29 and the inlet of a discharge hole 33 every time the rotating member 30 rotates once, is provided on the external surface of the rotating member 30, and the lubricating oil flowing in from the oil supply hole 29 is intermittently discharged into a drive chamber 7 via the groove 32 and the discharge hole 33.

    摘要： The object of the present invention is to offer an electric type swash plate compressor which is compact and reduced in weight and lightened, and which can efficiently cool down a motor chamber and a crank chamber. The compressor has an electric motor and a swash plate, which are respectively accommodated in the motor chamber and the crank chamber. In the compressor a communication route, which communicates a part except the discharge chamber communicating with an external refrigerant circuit in an inner refrigerant circuit within an outer casing with the motor chamber, is formed. The communication route is formed so as to pass through the crank chamber, and the refrigerant in lower temperature and lower pressure than discharge refrigerant is supplied into the motor chamber and the crank chamber. Accordingly, the improvement of cooling efficiency and the reduction of pressure resisting strength of the casing can be performed.

    摘要： A motor-driven compressor performs suction, compression, and discharge of refrigerant. The compressor has four cylinder bores and four pistons. A swash plate is integrally rotated with a drive shaft. A transmission mechanism transmits rotation of the swash plate to the pistons. The ratio of the discharge pressure to the suction pressure when the discharge displacement of the compressor is maximum, that is, the compression ratio, is in a range of 2 to 4.5. The compressor is constructed to permit the size of the motor to be minimized.

    摘要： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend in the housing. A pin is supported in each support hole. The ends of each pin are received in guide holes through the flange. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.

    摘要翻译： 一种改进的涡旋压缩机，其具有可旋转而不倾斜的可动涡旋件。 压缩机具有形成在壳体中的固定涡旋盘。 动涡旋盘容纳在壳体中并与固定涡旋件配合。 动涡旋盘通过曲柄机构由驱动轴驱动。 法兰形成在可动涡旋件的周边并垂直于驱动轴。 在壳体中形成凹槽。 凹槽比凸缘的厚度略宽。 凸缘可滑动地容纳在槽中。 支撑孔延伸到外壳中。 每个支撑孔支撑销。 每个销的端部通过法兰被接收在引导孔中。 由于凸缘和凹槽的接合防止可动涡旋件倾斜，所以销保持平行于导向孔并跟随引导孔的壁。 结果，避免了销和引导孔的不均匀磨损。

    摘要： An upper hold-down spring structure for a nuclear reactor fuel assembly. A hold down spring 20 mounted on an upper surface of an upper nozzle 11 of a fuel assembly for a pressurized water reactor is composed of an upper plate spring 21 having plastic spring characteristics and a lower plate spring 23, base ends of which are fixed with a fastening bolt 18 at a common position. The upper spring 21 and the lower spring 23 are made of precipitation hardened nickel base alloy and the thickness of the springs are determined so as to keep the stresses generated less sensitive to stress corrosion cracking.

    摘要： In a single-ended swash plate compressor, in which pistons are guided at both ends, the side clearance between the pistons and the cylinder bores on the guide side is made larger than the side clearance between the pistons and the said cylinder bores on the compression side. Preferably, this is approximately 2 to 10 times, that is approximately 10 to 100 .mu.m larger, or more preferably, 7 times larger.
