    Abstract: A cermet piston 36 is positioned to reciprocate within a ceramic sleeve 58 of a cryogenic refrigerator 12. The sleeve 58 forms a very tight clearance seal 67 with the piston 36 yet is allowed to float within a large gap 66 between piston housing 35 and the sleeve. The gap 66 allows the sleeve 66 to compensate for misalignment or distortions of the piston housing 35. Elastic seals 68, 70 prevent gas blow-by between the working space 18 of the piston 36 and the piston's dead space 19. The piston is connected to a motor drive mechanism through connecting rod 44 and helium lubricated wrist pin 48.

    Abstract: A shoe (15) arranged between a swash plate and a piston (10) of a swash plate type compressor for transmitting the rotating motion of the swash plate as a reciprocating movement to the piston (10), and a method for manufacturing the same. The shoe (15) is a single body having a hemispherical portion which slidably contacts a spherical recess formed on the piston, (10) and a planar end face (15b) which slidably contacts the end face of the swash plate. A method for manufacturing such a shoe (15) includes compressing a cylindrical blank in its axial direction and thereby plastically deforming one end of the blank against the inner surface of a hemispherical recess (10b) of a die, and plastically deforming the other end of the blank in a state where only the end face is restrained. According to this method a shoe (15) which incorporates a flank between the hemispherical portion making sliding contact with the recess (10b) of the piston (10) and the bottom end face (15b) making sliding contact with the swash plate can be readily manufactured. Another preferred embodiment of the method includes the steps of forming a hole having a predetermined size on the end face of the cylindrical portion of the blank beforehand and reducing the diameter of the hole opening by pressing and deforming the end face of the cylindrical portion so that the hemispherical portion is thus formed, or includes the steps of cutting the periphery of the end face of the cylindrical portion of the blank into a conical shape beforehand, and then pressing and deforming the conical portion of the blank thereby forming a hemispherical portion. This method can prevent the application of a local high load to the blank, and decrease the amount of material that must flow.

    Abstract translation: 布置在斜盘和旋转斜盘式压缩机的活塞（10）之间的滑板（15）以及用于将旋转斜盘的旋转运动作为往复运动传递到活塞（10）的滑座（15）及其制造方法。 鞋（15）是具有可滑动地接触形成在活塞上的球形凹部（10）的半球形部分和与斜盘的端面可滑动接触的平面端面（15b）的单体。 制造这种鞋（15）的方法包括在其轴向方向上压缩圆柱形坯料，从而使坯料的一端塑模地变形成与模具的半球形凹部（10b）的内表面，并使模具的另一端塑性变形 在仅限制端面的状态下的坯料。 根据该方法，在与滑动接触活塞（10）的凹部（10b）的半球形部分和与斜盘滑动接触的底端面（15b）之间形成有侧面的鞋子（15）可以容易地 制造。 该方法的另一优选实施例包括以下步骤：预先在坯料的圆筒部分的端面上形成具有预定尺寸的孔，并且通过使圆柱形部分的端面压迫和变形来减小孔开口的直径，使得 由此形成半球形部分，或者包括预先将坯料圆柱形部分的端面的周边切成圆锥形的步骤，然后将坯料的锥形部分压制和变形，从而形成半球形部分。 这种方法可以防止对坯料施加局部高负载，并减少必须流动的材料量。

    Abstract: A refrigerant compressor having a drive shaft rotatable to cause compression of a refrigerant gas, and a drive power transmission unit for transmitting a drive power from an external drive power source to the drive shaft, the drive power transmission unit having a pulley freely rotatably mounted around the drive shaft, a power transmitting element fixed to the drive shaft, and a shock absorbent rubber element arranged between the pulley and the power transmitting element for providing a positive engagement between the rubber element and the pulley, and between the rubber element and the power transmitting element. The shock absorbent rubber element absorbs a change in a load torque applied to the compressor before the torque change is transmitted to the external drive power source via the pulley, and disengages from at least one of the pulley and the power transmitting element when an excessive load torque is applied to the compressor to interrupt transmission of the excessive load torque from the compressor to the external drive power source.
