Abstract
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.
