涡旋压缩机
摘要：
本发明公开了一种涡旋压缩机。本发明中的涡旋压缩机(1)包括推压机构(75)和阻止逆流机构(35)。推压机构(75)具有背压室(53)和背压引入通路(80)，该背压室(53)面向动侧端板部(71)的背面，该背压引入通路(80)用来使即将与喷出口(64)连通的状态下的压缩室(23)和与喷出口(64)连通的状态下的压缩室(23)与背压室(53)连通。阻止逆流机构(35)允许背压引入通路(80)内的制冷剂从压缩室(23)流向背压室(53)，并且阻止背压引入通路(80)内的制冷剂从背压室(53)返回压缩室(23)。
摘要（英）：

A scroll compressor (1) is provided with a pressing mechanism (75) and a backflow prevention mechanism (35). The pressing mechanism (75) has a backpressure chamber (53) facing a back surface of a movable side end plate portion (71) and a backpressure introduction passage (80) for connecting the backpressure chamber (53) to a compression chamber (23) in a state immediately before a discharge port (64) is connected to the compression chamber (23) and in a state in which the discharge port (64) is connected to the compression chamber (23). The backflow prevention mechanism (35) permits a refrigerant in the backpressure introduction passage (80) to flow from the compression chamber (23) to the backpressure chamber (53) and prevents the refrigerant from returning from the backpressure chamber (53) to the compression chamber (23).
