Definitions

  • the piston 132 inserted into the cylinder 133 is coupled to the coupling section 136 .
  • the piston 132 is placed such that its axis crosses the axial direction of the crankshaft 140 .
  • the crankshaft 140 is placed such that its center axis extends in the longitudinal direction
  • the piston 132 is placed such that its center axis extends in the lateral direction. Therefore, the axial direction of the piston 132 is perpendicular to the axial direction of the crankshaft 140 .
  • the coupling section 136 is coupled to the piston 132 and to the eccentric shaft 141 of the crankshaft 140 .
  • the coupling section 136 transmits the rotational motion of the crankshaft 140 rotated by the electric component 120 to the piston 132 , and thereby the piston 132 reciprocates in the interior of the cylinder 133 .
  • a muffling space 163 a of the suction muffler 160 is formed by the muffler body 163 .
  • the tail pipe 161 is in communication with the internal space of the sealed container 101 , and serves to guide the refrigerant gas to the interior of the muffler body 163 .
  • the communication pipe 162 is located at the upper side of the muffler body 163 .
  • the communication pipe 162 is in communication with the compression chamber 134 via the suction hole 151 a of the valve plate 151 .
  • the communication pipe 162 guides the refrigerant gas from the interior of the muffler body 163 to the interior of the compression chamber 134 .
  • the refrigeration device 200 of the present embodiment incorporates the sealed compressor 100 of Embodiment 1.
  • the sealed compressor 100 since the sealed compressor 100 includes the gas inflow space 152 b in the interior of the sealed container, a decrease in the volumetric efficiency can be suppressed effectively by suppressing a temperature increase in the refrigerant gas.
  • the efficiency of the sealed compressor 100 is high.
  • electric consumption in the refrigeration device 200 can be reduced, and hence energy saving can be realized.
