First Claim
Patent Images
1. An orbital fluid pumping mechanism, comprising:
- a. an outer tube having an inner surface;
b. an inner member positioned substantially concentrically within the outer tube, the inner member having an outer surface;
c. a helical outer lobe operatively associated with the inner surface of the outer tube; and
d. a helical inner lobe operatively associated with the outer surface of the inner member, in operative association with the helical outer lobe.
