Claims

[Claims for Utility Model Registration] (1) A centrifugal pump that supplies oil from the bottom of a sealed case to a rotating shaft driven by an electric element, using the rotational centrifugal force of the rotating shaft. In a hermetic compressor having a pump part, the rotary shaft is surrounded along the circumferential direction of the pump part, one end part is fixed to the stator end face of the electric element, and the other end part is connected to the oil part. A hermetic compressor, characterized in that a pump cover is provided which is immersed in a pump cover and rotatably engages the rotating shaft so as to cover the rotating shaft from its lower end. (2) The pump cover is formed by pressing or bending to have approximately the same diameter as the outer periphery of the pump portion of the rotating shaft, and has elasticity so as to bias the rotating shaft from below. A hermetic compressor according to claim 1 of the patent registration claim.
