する圧縮機。 The lower shaft end surface 4 of the drive shaft 4 has an electric motor 2 installed in the upper part of the casing 1, a compression element 5 installed in the lower part, and an oil supply passage 41 formed inside the casing 1 in the axial direction.
2 is thrust-supported via a plate-shaped seat 7 attached to the frame 3, while the lower side of the oil supply passage 41 is in contact with the shaft end surface 42 and is arranged in an annular shape on the outer circumference of the drive shaft 4. a chamber 61 and the annular chamber 61
In the compressor, which is connected to the bottom oil sump 8 of the casing 1 via a pressurizing mechanism 6 having a pressurizing passage 62 extending radially toward the When the stator 21 is assembled so as to be displaced upward from the upper end surface of the stator 21, when the drive shaft 4 is driven, a downward force based on the electromagnetic force applied to the rotor 22 is applied to the lower shaft end surface 42. A compressor characterized in that the airtightness of the pressurizing mechanism 6 is improved by increasing the thrust load on the seat 7.
