摘要： A rotary compressor of the invention comprises an oil separating portion and an oil collecting portion located adjacent one end of a rotary shaft closely to a motor. An oil is separated through the oil separating portion and collected in the oil collecting portion in which the one end of the rotary shaft is submerged to lubricate a third bearing. The oil separating portion serves to separate oil mist which flows with gas flow. The one end of the rotary shaft is submerged in the oil as collected in the oil collecting portion under the influence of gravity to lubricate the bearing. This arrangement provides stable lubrication of the one end of the rotary shaft. The bearing is, thus, highly reliable while the rotary compressor is running at any speeds. Also, vibrations of the shaft can substantially be reduced particularly when the rotary compressor runs at a high speed.

摘要： In a gas pressure increasing system for increasing the pressure of a refrigerant gas or air having a scroll compressor, a condenser, a pressure reducing means and an evaporator or a scroll compressor and a gas cooler, an exhaust gas released from the scroll compressor after having its pressure increased by the scroll compressor itself is cooled and expanded to reduce its pressure to an intermediate pressure level to produce a gas of an intermediate pressure having a cooling capability. The gas of the intermediate pressure is used to provide a force for axially sealing an orbiting scroll member of the scroll compressor as well as to cool the scroll compressor and a motor.

摘要： A fixed scroll and an orbiting scroll each having an end plate and a wrap perpendicular to the end plate and having a mirror-like surface at the forward end are brought into intimate contact with each other such that the mirror-like surface of the wrap and the end plate of one scroll member are brought into sliding contact with the end plate and the mirror-like surface of the wrap of the other scroll member, respectively, to define fluid pockets between the two scroll members. The orbiting scroll is driven by a motor to move in orbiting movement relative to the fixed scroll to compress the fluid in the fluid pockets by gradually reducing the volume of the fluid pockets. A portion of the fluid in the fluid pockets is introduced into a hermetic container for the apparatus through communication ducts each formed on one side of the wrap of the orbiting scroll to increase the internal pressure of the hermetic container, to thereby force the orbiting scroll against the fixed scroll by the increased internal pressure of the hermetic container to provide airtight seal to the fixed and orbiting scrolls.

摘要： A scroll-type compressor constituted by a stationary scroll and a revolving scroll, and an electric motor for causing a revolving motion of the revolving scroll are disposed in a closed container. The scroll-type compressor has openings which are adapted to permit fluid compression pockets between two scrolls to be communicated with the space inside the closed container when the pressure in the pockets have been increased to a predetermined pressure intermediate between the suction and discharge pressures, so that the pressure in the closed container may be maintained at the same level as the above-mentioned predetermined pressure. The bottom part of the closed container constitutes an oil well where the lubricating oil is stored. This oil well is connected to the suction side of the compressor through an oil feed passage constituted by a capillary tube, so that the oil is fed to the compressor due to the pressure difference between the space inside the closed container and the inlet side of the compressor. An oil separating tank is disposed at the discharge side of the compressor. The lubrication oil separated by this oil separating tank is returned back into the closed container by the pressure differential between the discharge side of the compressor and the interior of the closed container.
摘要翻译：由静涡旋盘和旋转涡卷构成的涡旋式压缩机和旋转涡旋件的旋转运动的电动机配置在密闭容器内。涡旋式压缩机具有开口，当孔中的压力增加到吸入压力和排出压力之间的预定压力时，适于允许两个涡旋件之间的流体压缩袋与密封容器内的空间连通，因此密闭容器中的压力可以保持在与上述预定压力相同的水平。封闭容器的底部构成储存润滑油的油井。该油井通过由毛细管构成的供油路与压缩机的吸入侧连接，由于密封容器内部的空间与密闭容器的入口侧之间的压力差而将油供给到压缩机压缩机。油分离罐设置在压缩机的排出侧。由该油分离罐分离的润滑油通过压缩机的排出侧和密闭容器的内部之间的压力差返回到密闭容器中。
