Abstract
PURPOSE: To prevent drop of compression capacity by eliminating the over-compressed state through permitting the gas in the compression space to flow out to the discharge hole passing a check valve and by shutting the communication between the gas passage and compression chamber while there is no over-compression.
CONSTITUTION: When an over-compressed state is going to arise due to change of volumes of the male and female rotors 3, 4, the over-compressed gas opens immediately a check valve 36 to exhaust part of the high pressure gas in the compression chamber to the gas discharge hole 8 through an opening 31 and passage 30. Thus overcompression is hindered. When the over-compressed state is out, the check valve 36 is restituted to the closed position and the gas pressure of gas discharge hole 8 acts always on the gas passage 30, so that the check valve 36 blocks the compression chamber 1 from gas passage 30. Accordingly, compression and expansion of the gas in the compression chamber 1 is not transmitted to the gas staying in the gas passage 30, and thus drop of compression capacity can be prevented.
