More Information
Summary:The present invention is to reduce noise and vibration of scroll-type electric compressors. An annular space (74) divided and formed around a fixed scroll (25) by a step part (143), a second peripheral wall (142), a flange part (25f), and an outer peripheral wall (25c) is connected to an oil storage chamber (50). For this reason, the annular space (74) functions as the oil storage chamber. Therefore, it becomes possible to reduce the existing oil storage chamber (50) by the amount of the annular space (74). To that extent, it becomes possible to enlarge the space of an existing discharge chamber (40). Accordingly, pulsation of the refrigerant discharged into the discharge chamber (40) is suppressed. [과제] 스크롤형 전동 압축기의 소음 진동을 저감하는 것이다. [해결 수단] 단차부(143), 제2 주위벽(142), 플랜지부(25f) 및 외주벽(25c)에 의해, 고정 스크롤(25)의 주위에 구획 형성되는 환상 공간(74)이 저유실(50)에 연통되어 있다. 이 때문에, 환상 공간(74)이 저유실로서 기능한다. 따라서, 환상 공간(74)의 분만큼, 기존의 저유실(50)을 작게 하는 것이 가능해지므로, 그만큼, 기존의 토출실(40)의 공간을 크게 하는 것이 가능해진다. 따라서, 토출실(40)에 토출되는 냉매의 맥동이 억제된다.
