Abstract: A reciprocating compressor is provided. Bearing holes of a fluid bearing of the compressor may be positioned correspond to a full reciprocating region of a piston, to reduce/eliminate frictional loss and/or abrasion between a cylinder and the piston. The bearing holes may be concentrated at certain regions of the cylinder to stably support the piston through a full reciprocating range. Compression coil springs may maintain concentric alignment of the cylinder and the piston. Gas through holes may be radially formed at the piston to lower a pressure of a bearing space and allow refrigerant to be smoothly introduced into the bearing space through a gas pocket. A casing of the compressor may include an outer shell and an inner shell to attenuate vibration generated due to friction generated by operation of the reciprocating compressor.
Abstract translation: 提供往复式压缩机。 压缩机的流体轴承的轴承孔可以被定位成对应于活塞的完全往复运动区域，以减少/消除气缸和活塞之间的摩擦损失和/或磨损。 轴承孔可以集中在气缸的某些区域，以便在整个往复运动范围内稳定地支撑活塞。 压缩螺旋弹簧可以保持气缸和活塞的同心对准。 气体通孔可以在活塞处径向地形成，以降低轴承空间的压力，并允许制冷剂通过气囊平滑地引入轴承空间。 压缩机的壳体可以包括外壳和内壳，以减弱由于往复式压缩机的操作产生的摩擦而产生的振动。
