Rotary compressor and refrigeration apparatus

A rotary compressor comprising:

• a casing having an oil reservoir at its bottom;
• a compression mechanism housed in the casing;
• a drive shaft configured to drive the compression mechanism into rotation;
• an oil pump configured to suck up oil from the oil reservoir toward a storage space provided at a lower portion of the drive shaft;
• a first sliding member slidable on an outer circumferential surface of the drive shaft;
• and
• a second sliding member slidable on the outer circumferential surface of the drive shaft, the second sliding member being spaced from the first sliding member in an axial direction,
• the drive shaft having
• a first oil supply passage including
• a first axial passage configured to be offset from a center of rotation of the drive shaft in a radial direction, the first axial passage extending from the storage space in the axial direction, and
• a first connection passage configured to connect the first axial passage and a sliding surface of the first sliding member, and
• a second oil supply passage including
• a second axial passage configured to be offset from the center of rotation of the drive shaft in the radial direction, the second axial passage extending from the storage space in the axial direction at a position spaced from the first axial passage, and
• a second connection passage configured to connect the second axial passage and a sliding surface of the second sliding member.
