ABSTRACT:
A single screw mechanism with a reduced differential pressure applied to gaterotor teeth. This is accomplished by providing multiple tooth engagement of gaterotor teeth in a particular mainrotor compression chamber. Multiple tooth engagement makes possible the use of metallic gaterotor teeth and the elimination of gaterotor supports used to prevent the disengagement of gaterotor teeth due to high differential pressure.
