Abstract
Disclosed are a compression mechanism and a scroll compressor. The compression mechanism comprises an orbiting scroll and a non-orbiting scroll comprising a non-orbiting scroll end plate and forms a series of fluid chambers comprising an intermediate compression chamber. An exhaust communication space is provided on the second side of the non-orbiting scroll end plate, and the non-orbiting scroll end plate is provided with a pressure relief port which makes at least one intermediate compression chamber be in selective fluid communication with the exhaust communication space. An end plate surface on the first side of the non-orbiting scroll end plate is provided with an exhaust groove which is in communication with the pressure relief port, the pressure relief port can be in fluid communication with the at least one intermediate compression chamber through the exhaust groove.
