Abstract
Upper and lower housing portions combine to define a fluid-working area within the housing, and the portions are dissimilar. The lower housing portion is substantially circular, having a constant radius, whereas the upper housing portion is volute-shaped, having an increasingly extending radius and a continuously growing depth, in the direction of the outlet. Correspondingly, the lower housing portion has a continuously diminishing depth, in the direction of the outlet.
