a flow divider for use with fluent materials , such as raw sausage . the flow divider is a combination of at least two housing bodies with chambers defined by elliptical cylindrical sidewalls . hubs with transverse vanes have necked - down regions at one end that are rotatably mounted in a similarly - sized aperture in an endwall of each housing body . the vanes &# 39 ; tips follow the elliptical cylindrical sidewalls in the manner of a vane pump . sausage is conveyed from a conventional pump into the inlet of the flow divider , and flows through passages into inlet cavities , one inlet cavity per chamber , through the sub - chambers formed by the space between the vanes , and outlet cavities , one outlet cavity per chamber . the amount of sausage that flows through each chamber is equal due to the driving linkage between the hubs of each housing body .
