RECIPROCATING HERMETIC COMPRESSOR

PROBLEM TO BE SOLVED: To provide a reciprocating hermetic compressor with high efficiency in which temperature of an electromotive element is reduced.SOLUTION: The electromotive element 103 equipped with a stator 139 and rotor 159 and a compressing element 105 driven by the electromotive element 103 are accommodated in a hermetic container 101, and the rotor 159 is furnished at the upper end face with a plurality of forward facing vanes 161 formed radially along the radial direction, so that the forward facing vanes 161 function as a centrifugal blowing mechanism, to promote the heat radiation from the rotor 159 and the stator 139. Thus a reciprocating hermetic compressor with higher efficiency can be provided.
