1. A fluid delivery system comprising:

  • a fluid container;

    at least two pressurizing chambers in fluid connection with the fluid container, each of the at least two pressurizing chambers having an input and an output, the input of each of the at least two pressurizing chambers in fluid connection with a connector, wherein the at least two pressurizing chambers are disposed generally parallel to each other to form separate flow paths, a common outlet in fluid connection with the output of each of the at least two pressurizing chambers;

    an inlet valve in fluid connection with each of the at least two pressurizing chambers and operable to allow fluid to enter the at least two pressurizing chambers from the fluid container but to prevent fluid from flowing from the at least two pressurizing chambers into the fluid container;

    an outlet valve in fluid connection with each of the at least two pressurizing chambers and operable to allow fluid to enter the common outlet from the output of each of the at least two pressurizing chambers but to prevent fluid from flowing from the common outlet into the at least two pressurizing chambers; and

    a pumping mechanism permanently in fluid connection with the fluid container, the pumping mechanism comprising drive members cooperating with the at least two pressurizing chambers to pump fluid from the fluid container and to pressurize fluid within the at least two pressurizing chambers, wherein the drive members sequentially compress the pressurizing chambers to sequentially pass fluid through the separate flow paths and provide substantially continuous fluid flow to the common outlet.
