Abstract:
A motor-operated compressor includes a casing having a sealed internal space, a first scroll fixed in the internal space, and a second scroll engaged with the first scroll to form a plurality of compression chambers. The compressor also includes a frame fixed on an opposite side of the first scroll with the second scroll interposed therebetween, and a driving motor positioned on an opposite side of the second scroll. The compressor further includes a rotary shaft coupled to the second scroll in an off-centered manner and coupled to the driving motor. The first end portion of the rotary shaft forms a fixed end supported in the radial direction by members positioned on both sides of the second scroll. The second end portion of the rotary shaft forms a free end coupled to a rotor of the driving motor.
