ABSTRACT:
A rotary fluid pump is disclosed which uses rotating rollers running along a circular track to successively depress a plurality of lever arms which in turn operate pistons in a like number of pumps to thereby pump a fluid. The rollers are free to rotate on a frame, which frame rotates co-axially within the track. The rollers are carried on sleeves which slide on arms extending from the hub of the frame, such that the rollers are free to move radially outwardly, as well as inwardly, in response to inertial (i.e., centrifugal) forces associated with the rotation of the frame.
