ROTATORY COMPRESSOR AND REFRIGERATING CYCLE DEVICE

摘要

A rotatory compressor and a refrigerating cycle device are provided. The rotatory compressor includes a lubricating oil in an interior of a hermetically sealed housing, and an electric motor and a rotatory compressing mechanism disposed in the housing. An internal pressure of the housing is substantially equal to a suction pressure of the compressing mechanism. The compressing mechanism includes a first bearing and a second bearing at least one of which includes an exhaust muffler. A refrigerant of the exhaust muffler flows through the sliding vane chamber and is discharged from an exhaust pipe of the compressing mechanism.

1. A rotatory compressor comprising a lubricating oil in an interior of a hermetically sealed housing, and an electric motor and a rotatory compressing mechanism disposed in the housing, wherein
an internal pressure of the housing is substantially equal to a suction pressure of the compressing mechanism, and the compressing mechanism comprises:
an air cylinder defining a compressing chamber and a sliding vane chamber therein;a piston disposed within the compressing chamber;an eccentric shaft adapted to revolute the piston;a sliding vane disposed in the sliding vane chamber and adapted to reciprocate synchronously with the piston; anda first bearing and a second bearing slidably supporting the eccentric shaft and connected with the sliding vane chamber,wherein an exhaust muffler is within at least one of the first bearing and the second bearing, andwherein a refrigerant discharged from the exhaust muffler is adapted to flow through the sliding vane chamber and to be discharged from an exhaust pipe of the compressing mechanism.
