    • A swash plate compressor in which a drive shaft is rotatably supported in a cylinder block having a crank chamber. The swash plate is rotatably disposed on the drive shaft. Thrust bearings are individually fitted between the movable thrust receiving faces of the swash plate and the stationary thrust receiving faces of the cylinder block. As the drive shaft rotates, the swash plate likewise rotates and reciprocates a piston to compress a refrigerant gas. Annular movable ridges are formed on the front and rear side faces of the swash plate concentric around the drive shaft. Stationary ridges are formed concentrically with the movable ridges on the cylinder blocks to face the individually movable ridges. The stationary ridge has a smaller radius than that of the movable ridge. At the front and rear sides of the swash plate, the facing circumferential portions of the movable ridges and the stationary ridges are individually formed with movable and stationary thrust receiving faces for supporting the elastically deformable thrust bearings. At least one of the movable and stationary ridges are formed with escape faces so as to merge into the movable and stationary thrust receiving faces, for establishing escape faces normally between the corresponding thrust bearings. These escape faces expand and reduce the gaps when the thrust bearings are elastically deformed by the action of the swash plate due to the compression reaction forces caused by the reciprocation of the piston.
    • 旋转斜盘压缩机,其中驱动轴可旋转地支撑在具有曲柄室的气缸体中。 斜盘可旋转地设置在驱动轴上。 推力轴承分别安装在旋转斜盘的可动推力接收面和气缸体的固定推力接收面之间。 当驱动轴旋转时,斜盘同样旋转并使活塞往复运动以压缩制冷剂气体。 围绕驱动轴同心的旋转斜盘的前侧面和后侧面上形成环形活动脊。 固定脊与气缸体上的活动脊同心地形成以面对单独可移动的脊。 固定脊的半径比活动脊的半径小。 在斜盘的前侧和后侧,可移动脊和固定脊的相对周向部分分别形成有用于支撑可弹性变形的止推轴承的可移动和固定的推力接收面。 可移动和固定脊中的至少一个形成有逃逸面,以便合并到可动和固定的推力接收面中,用于在相应的推力轴承之间建立通常的逃生面。 当推力轴承由于活塞的往复运动引起的压缩反作用力而被旋转斜盘的作用弹性变形时,这些逃逸面膨胀并减小间隙。
