Claim:
1. A flow control assembly comprising: a fluid pump to pump fluid; a fluid flow resistor assembly to resist a flow of the fluid, the fluid flow resistor assembly comprising a first assembly component and a second assembly component; the first assembly component including a length of fluid channel, the fluid channel formed in a surface facing of the first assembly component to convey the fluid; the second assembly component movable with respect to the first assembly component, a surface facing of the second assembly component in contact with the surface facing of the first assembly component and the fluid in the fluid channel to retain flow of the fluid to be within the fluid channel of the first assembly component, the second assembly component including a first port and a second port; an opening of the first port positioned with respect to the fluid channel at a first location along the length of the fluid channel; an opening of the second port positioned with respect to the fluid channel at a second location along the length; wherein the second assembly component is rotatable about an axis with respect to the first assembly component, a first angular position of the second assembly component with respect to the first assembly component about the axis resulting in a full open setting of both the opening of the first port and the opening of the second port into a first channel segment of the fluid channel, the first channel segment being continuous; wherein the opening of the first port resides at a fixed radius with respect to the axis; and wherein the opening of the second port resides at the fixed radius with respect to the axis; wherein the fluid channel includes a second channel segment, a width of the fluid channel in the second channel segment varying to provide variable fluid flow resistance.
