ABSTRACT:
This invention relates to worm-type rotary fluid means, wherein a worm body having a plurality of helical screw threads and a plurality of grooves therebetween is engaged with a cylindrical pinion having a plurality of teeth. In this engagement, the fluid discharge volume is increased much greater than that of a conventional worm. This is due to the fact that the engagement of each pinion tooth of each worm groove has increased contact length and depth. Further, this causes a very stable engagement.
