Abstract:
Provided is a horizontal electric compressor that, even when tilted or the like, can secure a sufficient amount of lubricating oil for a compression mechanism unit and supply enough oil to a bearing of a rotary shaft positioned between the compression mechanism unit and an electric motor unit. The horizontal electric compressor has: a partitioning wall (111) that is provided integrally with a housing (110) to divide the inside of the housing (110) into a first accommodation chamber (113) and a second accommodation chamber (115), the first accommodation chamber accommodating an electric motor unit (10) that rotates a rotary shaft (200) and the second accommodation chamber accommodating a compression mechanism unit (30) driven by the rotary shaft (200) and having a higher pressure than the first accommodation chamber (113); and an oil supply passage (70) configured to utilize the pressure difference between the second accommodation chamber (115) and the first accommodation chamber (113) to supply lubricating oil O stored in the second accommodation chamber (115) to a first shaft hole (111b), which is a bearing of the rotary shaft (200) and is positioned between the electric motor unit (10) and the compression mechanism unit (30).
