Abstract (en)
[origin: EP4130478A1] This rotary compressor is provided with: a shaft extending along the axial line; a disk-shaped rotor that is centered on the axial line and that is fixed to the shaft; a pair of stators that respectively face the rotor from both sides of the axial line and that have disk-shaped back yokes centered on the axial line, teeth protruding from the back yokes, and coils wound around the teeth; a pair of annular cylinders that are centered on the axial line and that respectively axially come into contact with the stators; rotary pistons that eccentrically rotate together with the shaft; a pair of end plates that form compression chambers for housing the rotary pistons together with the back yokes by axially sandwiching the cylinders together with the stators; and a pair of bearings provided to the end plates and/or the back yokes.
