摘要： The variable capacity swash plate compressor of the present invention includes a rotary swash plate having an eccentric mass located opposite to the driving point of the swash plate with respect to the axis of the same. The mass distribution in the rotary swash plate is established such that, within a range in which the piston stroke is less than a predetermined value, a moment about a pivot point produced by the rotation of the swash plate becomes larger than a moment produced by the reciprocating motion of pistons, piston rods and the like and acting upon the swash plate, while, within a range in which the stroke is larger than the predetermined value, the former moment becomes smaller than the latter moment. Accordingly, it is possible to provide a compressor of the type in which its capacity control characteristics are improved over a wide shaft speed range.

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.

摘要： A moving vane type compressor has a cylinder which is made of a sintered material having a density of 6.6 to 7.6 and a composition consisting essentially of 0.6 to 0.8% of carbon, 1 to 2% of copper and the balance substantially iron. The cylinder is encased by a hermetic casing therebetween a high pressure chamber into which a refrigerant compressed by the compressor is discharged. Lubricating oil separated from the discharged refrigerant within the high pressure chamber and the lubricating oil suspended in the form of a mist by the refrigerant attach to the outer peripheral surface of the wall of the cylinder made of the sintered material. The oil attaching to the outer peripheral surface of the cylinder is forced by the refrigerant pressure acting thereon into the pores of the sintered material such as to block these pores, thus preventing the compressed gas in the cylinder from leaking outside through the pores.
