は前記密閉容器１に溶接固定されている。FIG. 1 shows a sectional view of a hermetic compressor according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an airtight container, inside which a motor element 4 consisting of a rotor 2 and a stator 3 and a compressor element 6 driven by the motor element 4 via a shaft 5 are arranged. ing. Also,
Oil 7 is collected at the bottom. The compressor element 6 is composed of a piston 8 integrated with the shaft 5 having a crank, and two bearing end plates 10, 11 that close openings at both ends of the cylinder 9. This one bearing end plate 10.11 each forms a pair, and the shaft 5
It also serves as a bearing support. 12 is a cover that constitutes the refrigerant discharge chamber 13 of the compressor element 6. Reference numeral 14 denotes an oil pump that guides the oil 7 to the sliding portion of the compressor element 6 through an oil supply passage 15 and an oil supply hole 16 formed around the axis of the shaft 5. 17 is a discharge pipe, and 18 is a suction pipe, which are fixed to the sealed container 1 by welding.
