Patent ID: 7344366

Claim:
A hermetic compressor, comprising: a case having a hermetic space and being connected with a suction tube which sucks gas with low temperature and pressure to the hermetic space and a discharge tube which discharges the compressed gas outside; a driving unit mounted at an upper portion of the case, for generating a driving force; and a compressing unit mounted at a lower portion of the case and connected to the driving unit by a rotational shaft so as to compress the gas with low temperature and low pressure sucked into the case through the suction tube by a rotational force generated from the driving unit and discharge the gas through the discharge tube, the compression unit including: an eccentric ring which is fixed at a lower portion of the rotational shaft; a cylinder in which the eccentric ring is rotably arranged, a compression space where gas is compressed is formed, a suction passage for guiding gas sucked into the case to the compression space is formed at a side of the compression space; and a lower frame which is fixed on the lower side surface of the cylinder so that it can be sealed, and in which a high pressure chamber through which gas compressed in the compressing space of the cylinder is temporarily stored and is discharged to the discharge tube, the high pressure chamber being distinct from the compression space and the discharge tube.
