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： A spool 9 is connected to the rotating shaft 1 so that the spool 9 is slidable with respect to the shaft 1, while the rotating movement of the shaft 1 is transmitted to the spool 9. The spool 9 is formed with a first recess 9-3 of a reduced circumferential extension for obtaining a reduced compression capacity and a second recess 9-4 of an increased circumferential extension for obtaining a full capacity of the compressor. An intake pressure is always opened to a side of the spool, while an intermediate chamber is formed on the other side of the spool. A spring 10 is arranged for causing the spool 9 to be moved toward the intermediate pressure chamber. At the instant the compressor is brought into operation, introduction of the intake gas occurs via the first recess 9-4, thereby obtaining a compression capacity of 3 to 5% compared to the full capacity of the compressor.

摘要： A swash plate type compressor having pistons, each defining on opposite sides compression chambers 38 and 39. The cross sectional area of the operating chamber 39 located adjacent the driving source is larger than the cross sectional area of the operating chamber 38 located away from the driving source in such a manner that the axial force F0 generated in a rotating shaft 5 due to the difference between the pressure at the swash plate chamber and the atmospheric pressure is substantially canceled by the axial forces F1 and F2 generated in the rotating shaft due to the refrigerant pressure acting on the piston 8 in the operating chambers 38 and 39.

摘要： A fluid machine has a scroll type expansion device which is operated by a high temperature high pressure refrigerant. The refrigerant is heated by use of waste heat from an engine for a vehicle. The fluid machine further has a motor generator for generating electric power when it is driven by a rotational force produced at the expansion device, wherein a rotating shaft of the motor generator is coupled to a movable scroll of the expansion device via a crank mechanism. A biasing member is provided for biasing the crank mechanism in a direction that the movable scroll wrap is separated from a contact in a circumferential direction with a fixed scroll wrap. Pressure of the refrigerant in a working chamber in the center portion is thereby equalized to the pressure in the outer peripheral portion, at a startup period of the expansion mode.
