摘要： Disclosed is a reciprocating compressor. As bearing holes which constitute a fluid bearing are formed to correspond to an entire region of a piston, a frictional loss or abrasion between a cylinder and the piston can be prevented. As the bearing holes are formed at a lower part of the cylinder in a concentrated manner, the piston can be stably supported. As compression coil springs are configured as resonant springs, the cylinder and the piston can be easily aligned with each other in a concentric manner, and performance of the reciprocating compressor can be enhanced. As gas through holes are formed at the piston in a radial direction, a pressure of a bearing space can be lowered and thus a refrigerant can be smoothly introduced into the bearing space through a gas pocket. As a shell has a double structure of an outer shell and an inner shell, vibrations generated from the reciprocating compressor can be attenuated by friction occurring between the outer shell and the inner shell. As a casing has a double structure of an outer shell and an inner shell, vibration noise generated from the reciprocating compressor can be attenuated.
摘要翻译： 公开了一种往复式压缩机。 由于构成流体轴承的轴承孔形成为与活塞的整个区域对应，所以能够防止气缸与活塞之间的摩擦损失或磨损。 由于轴承孔以集中的方式形成在气缸的下部，所以活塞能够被稳定地支撑。 由于压缩螺旋弹簧构造为共振弹簧，所以汽缸和活塞可以以同心方式容易地彼此对齐，并且可以增强往复式压缩机的性能。 由于气体通孔沿径向形成在活塞上，所以可以降低轴承空间的压力，从而可以通过气囊将制冷剂平稳地引入轴承空间。 由于外壳具有外壳和内壳的双重结构，所以由往复式压缩机产生的振动可以通过外壳与内壳之间发生的摩擦而衰减。 由于壳体具有外壳和内壳的双重结构，因此可以减小往复式压缩机产生的振动噪音。
