Pump body assembly, compressor and air conditioner

A compressor, comprising a pump body assembly, wherein the pump body assembly comprises:

• a crankshaft comprising a first eccentric portion, a support shaft and a second eccentric portion which are arranged at intervals in an axial direction;
• and
• a first baffle plate and a second baffle plate which are arranged in sequence between the first eccentric portion and the second eccentric portion,
• wherein a first round hole is arranged on the first baffle plate, and the support shaft is arranged in the first round hole, so that the first baffle plate and the support shaft form a baffle plate bearing, and the baffle plate bearing has a stress relief structure for reducing a contact stress between the support shaft and the first baffle plate;
• and
• the stress relief structure comprises a second flexible groove arranged on an end face of the first baffle plate facing toward the second baffle plate, and the second flexible groove is arranged on a side of the first baffle plate close to an inner edge of the first round hole.
