<p>PURPOSE:To eliminate the need of bringing a roller into an eccentric state, to reduce production of vibration due to rotation of a roller, to reduce the size of a compressor, and to reduce the number of high-precise parts, by a method wherein the roller is rotated by a drive shaft, and a refrigerant is compressed in the direction of the roller shaft. CONSTITUTION:When a roller 8 is rotated by means of a drive shaft 4, a refrigerant is sucked in a hollow chamber 10 through a suction port 7 in a way that a level on a sloped surface is lowered orderly from a to[p part 12 of a protuberant part 11 formed on the surface on the main bearing 6 side of the roller 8. The refrigerant is compressed by a compressing part 15, being the side which the top part 11 of the protuberant part 12 of a hollow chamber 10 approaches, as a top part 12 is caused to approach a blade 13 by means of the roller 8. When the pressure of the refrigerant is increased to a given value, a delivery valve 19 is opened, and the refrigerant is discharged through a discharge port 18. This constitution, since the refrigerant is compressed in the direction of the shaft of the roller 8, eliminates the need of bringing the roller 8 into an eccentric state, and enables reduction of production of vibration and the size of a compressor.</p> |
