摘要： PROBLEM TO BE SOLVED: To solve the following problems: stable back pressure is secured by arranging a back pressure control valve controlling differential pressure, a throttle flow passage part, and an intermittent flow passage part that intermittently connecting, by orbiting motion of an orbiting scroll, in a back pressure chamber fluid outlet passage connecting a back pressure chamber with a suction chamber or a compression chamber, while communication time between the back pressure chamber and the suction chamber (or the compression chamber) is reduced and insufficient oil may be supplied to the compression chamber due to the intermittent flow passage part; while when no intermittent flow passage part is arranged, pressure pulsation in a back pressure chamber fluid outlet passage is large, the back pressure control valve abnormally opens and no back pressure is generated.SOLUTION: An enlarged space is formed along a path formed from the back pressure chamber to a suction space or the compression chamber, on a side closer to the back pressure chamber than the back pressure control valve, and has a cross-sectional area 1.5 times or more an inlet of the path, so that an inlet thereof is normally opened without being closed by the orbiting scroll.
摘要翻译：要解决的问题：为了解决以下问题：通过设置控制差压的背压控制阀，节气门流路部分和间歇连通的间歇流道部分来确保稳定的背压，通过轨道运动在背压室流体出口通道中的回转涡旋件，其连接背压室与吸入室或压缩室，同时背压室和吸入室（或压缩室）之间的连通时间减小，并且不足的油可能由于间歇流路部分而被供应到压缩室; 而在不设置间歇流路部的情况下，背压室流出口的压力脉动大，所以背压控制阀异常打开，不产生背压。解决方案：沿着背压室形成的路径形成一个扩大的空间，该吸入空间或压缩室在靠近背压室的一侧比背压控制阀更为横截面面积为通道入口的1.5倍以上，使得其入口通常被打开而不被绕动涡旋件关闭。版权所有（C）2013，JPO＆INPIT
