  • Patent number: 10371147
    Abstract: An electrically-driven compressor including a housing, an electric motor, a compression mechanism, a cover member, a motor drive circuit, and a sealing member is disclosed. The electric motor is accommodated in the housing. The compression mechanism is accommodated in the housing and operated by the electric motor. The cover member is attached to the housing. The housing and the cover member form an accommodation portion including an accommodation space therein. The motor drive circuit is accommodated in the accommodation space and drives the electric motor. The sealing member is arranged between the housing and the cover member to seal the accommodation space. The sealing member includes an elastic seal portion that comes into close contact with the housing and the cover member. A core sustains the shape of the seal portion in conformance with the circumferential edge of the accommodation space.

  • Patent number: 7556483
    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.

  • Publication number: 20060263227
    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.
