Abstract
Apparatus and methods to control fluid flow in a downhole tool are disclosed. A disclosed example system includes a hydraulically actuatable device having a cavity for receiving pressurized hydraulic fluid stored by a reservoir, a first and a second hydraulic pump, a motor and means for selectively flowing hydraulic fluid from the outlet of at least one of the first and second pumps to the at least one cavity. The first and second hydraulic pumps include an inlet fluidly coupled to the reservoir and an outlet fluidly coupled to the cavity, and the motor is operatively coupled to at least one of the pumps.
