Patent number: 7458788Abstract: A scroll fluid machine is capable of readily providing a back-pressure chamber having an increased pressure-receiving area and yet capable of being reduced in size. A fixed scroll member is secured to a casing. An orbiting scroll member is provided at a position facing the fixed scroll member. A holder is provided at the back of the orbiting scroll member, and a coupling member is provided to face the orbiting scroll member across the holder. The coupling member couples together the orbiting scroll member and a driving shaft and performs an orbiting motion together with the orbiting scroll member. A back-pressure plate is provided at the back of the orbiting scroll member, and a back-pressure chamber is formed between the back-pressure plate and the holder.Type: GrantFiled: September 27, 2007Date of Patent: December 2, 2008Assignee: Hitachi, Ltd.Inventors: Kiminori Iwano, Yuji Komai, Kazutaka Suefuji, Koji Fukui, Toshitsugu Suzuki, Junichi Nagasawa, Susumu Sakamoto, Katsushi Hidano, Kazunari Komatsu
