Abstract (en)
[origin: EP3354902A1] A rotary compressor (100) includes a casing (1), an electric motor (2) and a compression mechanism (3), in which the electric motor (2) includes a stator core (21) and a rotor core (21), the compression mechanism (3) includes an air cylinder assembly (31) and a main bearing (32) connected to a side end face of the cylinder assembly (31) adjacent to the electric motor (2), the largest distance between a side end face of the stator core (21) adjacent to the first end wall (111) and the first end wall (111) is denoted by Dst, the smallest distance between a side end face of the rotor core (21) adjacent to the first end wall (111) and a side end face of a flange portion (321) of the main bearing (32) at one side adjacent to the first end wall (111) is denoted by Drt, in which Dst and Drt satisfy a relationship: 0.335‰¤Dst/Drt‰¤0.838.
