1. A compression mechanism, comprising:
an orbiting scroll, wherein the orbiting scroll comprises an orbiting scroll end plate and an orbiting scroll blade formed on a side of the orbiting scroll end plate; and
a non-orbiting scroll, wherein the non-orbiting scroll comprises a non-orbiting scroll end plate with a first side and a second side, a non-orbiting scroll blade formed on the first side of the non-orbiting scroll end plate and a central exhaust port formed at the center of the non-orbiting scroll end plate, the non-orbiting scroll and the orbiting scroll cooperate to form a series of fluid chambers between the non-orbiting scroll and the orbiting scroll during the operation of the compression mechanism, the series of chambers comprise a central compression chamber in communication with the central exhaust port, an air suction chamber in communication with an air suction port of the compression mechanism, and an intermediate compression chamber located between the central compression chamber and the air suction chamber;
wherein an exhaust communication space is provided on the second side of the non-orbiting scroll end plate, the exhaust communication space is in communication with the central exhaust port, 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,
wherein 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 selectively communicates with the at least one intermediate compression chamber through the exhaust groove.
