Patent number: 9812919Abstract: The purpose is to provide an inverter-integrated electrically driven compressor by which the danger of contacting an inverter device while power is being applied can be overcome in a reliable manner, without the need to provide any extra components, such as safety devices or the like. In this inverter-integrated electrically driven compressor, the inverter device is arranged housed within an inverter housing part hermetically sealed by a cover, and power and communication lines from an external power supply and a control device are connectable to the inverter device through connectors. The connector on the compressor side is furnished to the cover side, and at least one bolt of a fastening means for fastening the cover to the inverter housing part is furnished at location covered by the connector on the power line side, making access impossible, when the connector on the power line side has been coupled to the connector on the compressor side.Type: GrantFiled: May 22, 2013Date of Patent: November 7, 2017Assignee: MITSUBISHI HEAVY INDUSTRIES AUTOMOTIVE THERMAL SYSTEMS CO., LTD.Inventor: Noriaki Arashi

Patent number: 9784261Abstract: Provided is a gasket (30), which is used in a motor-driven compressor including an inverter housing, including a flat core of metal (31) and an elastic foamed material (32) so disposed as to cover both surfaces of the core (31), and the gasket (30) has embossed recesses and projections (33) with predetermined shapes. It is possible to enhance sealing performance to seal the inverter housing by using this gasket (30). A motor-driven compressor using this gasket (30) enhances vibration prevention.Type: GrantFiled: August 30, 2011Date of Patent: October 10, 2017Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Takayuki Hagita, Shinichi Takahashi, Takeshi Hirano, Noriaki Arashi, Takayuki Watanabe
