摘要： A first swash plate 18 is coupled to a drive shaft 16 to be rotatable integrally with the drive shaft 16. Single head pistons 23 are coupled to the first swash plate 18 via shoes 25A, 25B. Rotation of the drive shaft 16 rotates the first swash plate 18, which causes the pistons 23 to reciprocate and compress refrigerant gas. The first swash plate 18 supports an annular second swash plate 51 to be rotatable relative to the first swash plate 18 via a ball bearing 52. The second swash plate 51 is arranged between the first swash plate 18 and the shoes 25B that receive a compressive load to be slidable with respect to the first swash plate 18 and the shoes 25B. Therefore, the first swash plate reliably slides with respect to the second swash plate.

摘要： A compressor has suction reed valves each of which includes a fixation portion fixed to the valve base plate, a basal portion that extends from the fixation portion and is separable from the plate, and a valve flap extending from the basal portion toward the distal end to selectively open and close the suction port. Each suction port has a shape elongated in the width direction, which is orthogonal to the longitudinal direction. The width of the basal portion is greater than that of the suction port. Each valve flap includes an opening-closing portion facing the corresponding suction port and stoppers, which project from the ends in the width direction. The side edges in the width direction are continuous from the stoppers to the basal portion to gradually approach the suction port. The cylinder block has pairs of recessed retainers. The stoppers contact the retainers.

摘要： A maximum inclination setting projection comes into contact with a rotary support in a region closer to a point corresponding to a top dead center than an imaginary two-part dividing plane, thereby establishing a maximum angle of inclination of a cam plate. Thus, a hinge mechanism is not required to support any proportion of a compressive load in the region closer to the point corresponding to the top dead center than the imaginary two-part dividing plane when the cam plate is in its maximum angle of inclination. Bulbous parts of guide pins do not come in contact with halves of cylindrical inside surfaces of guide holes closer to the rotary support, and there is made a clearance between the bulbous part of the guide pin and the guide hole and between the bulbous part of the guide pin and the guide hole, interrupting transmission of the compressive load between them.

摘要翻译： 最大倾斜设定突起与旋转支撑件接近于比假想的两部分分割平面更靠近与上止点相对应的点的区域，从而建立凸轮板的最大倾角。 因此，当凸轮板处于其最大倾角时，不需要铰链机构来支撑在靠近与上止点相对应的点处的压缩载荷的任何比例超过假想的两部分分割平面。 引导销的球形部分不会与更靠近旋转支撑件的导向孔的圆柱形内表面的一半接触，并且在引导销的球形部分和引导孔之间以及在引导孔的球形部分之间形成间隙 导向销和导向孔，中断它们之间的压缩载荷的传递。

摘要： A swash plate compressor that prevents a slide plate from being separated from a swash plate. The compressor includes a drive shaft. A slide plate is rotatable relative to the swash plate. Two shoes is arranged on the swash plate and the slide plate. A bearing arranged between the swash plate and the slide plate and in between the shoes. A piston is connected to the swash plate and the slide plate by the shoes and is reciprocated to compress gas. The swash plate includes a swash plate support surface, and the slide plate includes a slide plate support surface, in which each surface is for contacting the bearing. The swash plate is formed so that a clearance between the swash plate support surface and the slide plate support surface increases radially inwardly of the swash plate and the slide plate.

摘要： Suction ports corresponding to individual cylinder bores are formed in a partition plate. A refrigerant feeder channel is provided on a rear wall of a rear housing whose internal space is partitioned chiefly into a suction chamber and a discharge chamber. A structural wall of the refrigerant feeder channel constitutes an integral part of the rear housing. The refrigerant feeder channel is formed from an outer cylindrical wall of the rear housing, extends across the discharge chamber and opens into the suction chamber. An outflow opening of the refrigerant feeder channel has a slanting edge so that it opens toward the partition plate. The outflow opening is so positioned that its center lies on an axis of a rotary shaft.
