Patent number: 9541310Abstract: A sealed compressor includes a centrifugal impeller above a rotor to synchronously rotate. A refrigerant rises through a rotor air hole, flows in an upper space, and flows out from a discharge pipe. The centrifugal impeller includes an oil separation plate on the rotor, and plural vanes standing on the oil separation plate, and forms inter-vane flow passages between adjacent vanes, and a vane inner flow passage that guides refrigerant from the rotor air hole to inner entrances of the inter-vane flow passages. Outer exits of the inter-vane flow passages are disposed along an entire circumference, and refrigerant increased in pressure while passing through the inter-vane flow passages flows out from the outer exits to the upper space. The oil separation plate closes a short-circuit passage through which the refrigerant directly flows from the vane inner flow passages to the discharge pipe without passing through the inter-vane flow passages.Type: GrantFiled: January 16, 2013Date of Patent: January 10, 2017Assignee: Mitsubishi Electric CorporationInventors: Tetsuhide Yokoyama, Shogo Moroe, Yoshinori Shirafuji, Teruhiko Nishiki, Taro Kato, Hideaki Maeyama, Hiroki Nagasawa, Keisuke Shingu
