摘要： A thrust bearing mechanism receives thrust force which is an element force of a compression counter-force acting on a movable scroll member, and which is perpendicular to the orbital direction of the movable scroll member. The thrust bearing mechanism includes plural substantially cylindrically-shaped first and second rollers. The first roller rotates in one direction, and the second roller rotates perpendicularly to the first roller. Thus, the contact surface area of the rollers is larger than that in which spherical rollers receive the thrust force, thereby suppressing the compressor from being enlarged to accommodate increased thrust forces, and improving the reliability and durability of the compressor.

摘要： A CO.sub.2 compressor is disclosed for forcing and moving a lubricant under discharge pressure. If the oil path is reduced in size or a pressure reducing part is inserted to handle the large differential pressure caused between the discharge pressure and the intake pressure, the oil path would become liable to be easily clogged by foreign matter. In view of this, an intermittent oil supply mechanism is formed in the oil path using the sliding contact portion between a fixed member of the compressor body and a movable member. Thus, the substantial lubrication time period is shortened and the amount of oil supplied is limited.

摘要： A compact, lightweight electric motor driven compressor suitable for an air conditioning system using a CO2 refrigerant is disclosed. The thickness of a motor casing is reduced by using the gaps formed in the motor portion in a motor casing as a part of a low-pressure intake chamber, while forming a part of the discharge chamber by utilizing the annular gap between the inner surface of a pump casing and the outer surface of a compressor portion. In the case where CO2 refrigerant is used, the compressor portion can be reduced in size and therefore a dead space is generated due to the difference in size with the motor casing. Since this dead space is used as a discharge chamber, the capacity of the discharge chamber can be increased to suppress the discharge pulsation.
摘要翻译：公开了一种适用于使用CO 2制冷剂的空调系统的紧凑，重量轻的电动机驱动的压缩机。电动机壳体的厚度通过使用形成在电动机壳体中的电动机部分中的间隙作为低压吸入室的一部分而减小，同时通过利用在泵壳体和压缩机部分的外表面。在使用二氧化碳制冷剂的情况下，压缩机部分的尺寸可以减小，因此由于与电动机壳体的尺寸的差异，会产生死角。由于该死区被用作放电室，所以可以增加放电室的容量以抑制放电脉动。

摘要： In a hybrid type compressor, a one-way clutch is provided between a magnet rotor and a rotor shaft for allowing rotational driving force generated by an electric motor unit to be transmitted only from a rotor to a shaft. Thus, the rotational driving force generated by a vehicle engine is not transmitted from the rotor shaft to the magnet rotor. That is, an inertia moment of a rotational system with respect to a vehicle engine is made small, thereby reducing the impact vibration when the clutch mechanism engages.

摘要： A hybrid type compressor is provided that is drivable by an electric motor and an external driving source. The hybrid type compressor includes a housing and a compression mechanism. A shaft is rotatably supported by the housing for transmitting rotational driving force to the compression mechanism. The electric motor unit generates rotational driving force for rotating the shaft and includes a stator fixed to the housing and a rotor rotatable with respect to the stator. The hybrid type compressor also includes a pulley for receiving rotational driving force generated by the external driving source and for transmitting the rotational driving force to the shaft. Additionally, a one-way clutch is provided between the pulley and the shaft for allowing the rotational driving force generated by the external driving source to be transmitted only from the pulley to the shaft.

摘要： A swash plate type variable capacity compressor having rotary valves that rotate together on a rotating shaft. The rotary valves are arranged on the shaft in such a manner that, upon one complete rotation, the rotary valves are connected, in sequential manner, for respective rotating angles, with circumferentially spaced piston chambers via respective intake passageways on the rotary valves. The arrangement between the intake passageways and the piston chamber changes in accordance with the axial position of the rotary valves on the shaft. Control of the rotating angle varies the effective volume of the piston chambers, thereby continuously varying the compressor capacity.

摘要： In a vehicle air conditioner having a refrigerant cycle using carbon dioxide as refrigerant, a displacement of a compressor is changed and controlled, so that an air temperature immediately after passing through an evaporator becomes approximately 0° C., and it can prevent a refrigerant amount discharged from the compressor from being larger than a predetermined flow amount. Because the refrigerant amount discharged from the compressor is controlled to be not larger than the predetermined flow amount, it can prevent a high-pressure side refrigerant pressure and a high-pressure side refrigerant temperature from being excessively increased in the refrigerant cycle.
