Fluid supply device

A fuel supply device according to the present invention comprises a first fuel pump (21) for forcing fuel from a fuel tank (11) to a fuel passage (14), a first electric motor (23) for driving the first fuel pump (21), a second fuel pump (22) for forcing fuel from the fuel tank (11) to the fuel passage (14), a second electric motor (24) for driving the second fuel pump (22), a supply flow rate sensor (26) for detecting flow rate in the supply passage (14), and a control device (25) for controlling the flow rate in the supply passage (14) to follow a desired value thereof, by regulating rotational speeds of the first and second electric motors (23, 24) depending on a difference between the desired value and a detected value of flow rate in the supply passage (14).
