Abstract
The operating chambers in a pulsator have axially movable partitions that make it possible to vary their capacities. The primary effect of varying the capacities is to vary the rate of the pulsator in a very simple way. It is also possible, however, to eliminate any wobble that may occur by varying the capacities of the chambers individually.
