摘要： A variable-displacement compressor includes a wobble member for driving a pistons, and a rotation member for wobbling the wobbling member, a first support portion for supporting a wobbling member in such a manner that the angle of wobbling of the wobbling member is variable, and a second support portion for supporting said rotation member in such a manner that the angle of tilt of said rotation member relative to a main shaft is variable. With this construction, unbalanced inertia forces can be reduced greatly, thereby providing the variable-displacement compressor which produces less vibrations and noises.

摘要： A scroll-type fluid machine is provided with a plurality of liquid-confining pockets formed in the sliding surface of the end member of either one of orbiting and stationary scrolls. In operation, a high liquid pressure is generated in the pocket or pockets positioned in the region where a localized high axial urging force is exerted during operation, so that the localized high axial urging force acting on the two scrolls is partially or fully negated.

摘要： A variable displacement swash plate type compressor is suitable for use as a refrigerant compressor for automobile air conditioner. The compressor includes pistons, an oscillating member for driving the piston, a rotating member for oscillating the oscillating member, a plate member for imparting a rotational force to the rotating member, and a main shaft connected to the plate member. A member, having a spherical or cylindrical surface portion and a flat surface portion, is provided between the rotating member and the plate member in such a manner that it is slidably in contact with both of the rotating member and the plate member. Also, movement of the oscillating member is defined by contact of the oscillating member with a stationary member. Consequently, it is possible to provide a variable displacement swash plate type compressor which assures reliable capacity control at a high-speed rotation and which vibrates and wears less. Furthermore, it is possible to prevent application of a thrust load to the drive shaft.
