Abstract:
A pump assembly is provided and includes a housing having first, second and third pairs of fluid openings and first, second and third rotary pumps, which are co-rotatable about a common longitudinal axis defined through the housing to drive fluid flow relative to the first, second and third pairs of fluid openings, respectively. The first rotary pump includes an input member receptive of rotational drive energy for the first, second and third rotary pumps.
