Abstract
A compressor housing defines a motor accommodating chamber. The pressure in the motor accommodating chamber is equal to the pressure in a suction chamber. A first reservoir chamber is located in a discharge chamber. A second reservoir chamber is defined about the discharge chamber. A communicating passage connects the first reservoir chamber with the second reservoir chamber. A restrictor is located in the communicating passage. An oil return passage connects the second reservoir chamber with the suction chamber. A connecting passage connects the motor accommodating chamber with the suction chamber. Therefore, leakage of electricity is prevented.
