Two identical impellers, 1 and 2, rotate about fixed axes A and B and have two teeth d each with profiles made up of portions of cycle curves. When impellers 1 and 2 rotate, fluid (air or liquid) is continuously delivered in the direction of arrows a and b. The suction and discharge chambers are separated by imparting special profiles to impellers 1 and 2. The impellers are driven by two meshing identical gears keyed to the shafts of impellers 1 and 2.
