Abstract
A high pressure dome type rotary compressor including a casing and a compression mechanism disposed in the casing to compress gas in a cylinder chamber. The compression mechanism has a discharge port and a discharge valve. The discharge valve is opened in a discharge process and is closed during a period from when the discharge process is finished to when a next compression process is started. The compressor is arranged such that high pressure gas discharged from the discharge port in the discharge process is discharged outside the casing through space in the casing. An oil feed path is arranged to feed lubricant oil contained in a bottom of the casing to an inside of the discharge port in a period from a point in time in the discharge process to when the compression process is started.
