摘要: A pump housing is provided with a conduit extending through the between inlet and outlet. device disposed within in communication to fluid therethrough. flow meter also monitor rate conduit. The generates signals related which are fed back control operable device. may include pair of meshed modified elliptical gears. gears based on true shape, bulged portions added major minor axes shape. have involute teeth that relatively thick adjacent axis thin axis.
