COMPRESSOR
First Claim
1. A compressor comprising:
- a shaft extending in axial directions thereof;
an impeller secured to one end of the shaft;
a first bearing action member provided at the one end of the shaft;
a second bearing action member provided at an opposite end of the shaft that is opposite to the one end of the shaft;
a first bearing configured to act on the first bearing action member and support the first bearing action member in one axial direction of the axial directions and in a radially inward direction of the shaft; and
a second bearing configured to act on the second bearing action member and support the second bearing action member in another axial direction of the axial directions, which is opposite to the one axial direction, and in the radially inward direction of the shaft.

7. A compressor comprising:
-
a shaft extending in axial directions thereof; a first impeller secured to one end of the shaft and including, at one side thereof, first blades configured to guide a flow of fluid and, at an opposite side thereof, a first action surface with a tapered shape that becomes narrower toward a distal end; a second impeller secured to an opposite end of the shaft that is opposite to the one end of the shaft to which the first impeller is secured, the second impeller including, at one side thereof, second blades configured to guide the flow of the fluid and, at an opposite side thereof, a second action surface with a tapered shape that becomes narrower toward a distal end; and a first bearing and a second bearing configured to act on the first action surface and the second action surface, respectively, wherein the first action surface and the second action surface face each other, wherein the first bearing acts on the first action surface and supports the first impeller in one of the axial directions and in a radially inward direction of the shaft, and wherein the second bearing acts on the second action surface and supports the second impeller in another axial direction, which is opposite to the one axial direction, and in the radially inward direction of the shaft.
