ABSTRACT:
The present invention comprises two complementary gear wheels each of which have a plurality of vanes fixed to the interior faces thereof. The vanes are interlocked in overlapping relationship and the gears are free to rotate independently of one another at different speeds so as to cause the gaps or chambers between the vanes to vary depending upon the changes in the relative speed of the two wheels with respect to one another. Various means are provided for driving the two wheels independently of one another at varying speed ratios. Chain and sprockets may be used, or complementary gears of varying shapes and having different numbers of lobes may be used to accomplish different patterns of movement of the two wheels with respect to one another. Furthermore, variable drive means may be provided for driving the two wheels so as to provide positive control of the variance in the movement of the two wheels.
