A fluid delivery system (100, 200, 300) comprising a pressurizing mechanism, the pressurizing mechanism comprising: a body (102, 302, 402) having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body, the plunger rod configured to operatively engage a fluid container; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body; a first valve in communication with the first chamber configured to form a vacuum within at least the first chamber when the movable member is moved toward the second end of the body; a second valve in communication with the second chamber configured to: a) have air expelled therefrom when the movable member is moved toward the second end of the body; b) form a vacuum within the second chamber that balances the vacuum in the first chamber when the movable member is advanced toward the first end of the body; and c) allows atmospheric pressure to enter the second chamber when opened; and an actuator configured to actuate the pressurizing mechanism to cause the movable member to move towards the first end of the body and forcing the plunger rod to move within the fluid container, the actuator being connected to a fluid dispensing end of the fluid container and being switchable between a first state in which fluid in the fluid container is prevented from flowing through the fluid dispensing end and a second state in which the fluid can flow through the fluid dispensing end. a body (102, 302, 402) having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body, the plunger rod configured to operatively engage a fluid container; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body; a first valve in communication with the first chamber configured to form a vacuum within at least the first chamber when the movable member is moved toward the second end of the body; a second valve in communication with the second chamber configured to: a) have air expelled therefrom when the movable member is moved toward the second end of the body; b) form a vacuum within the second chamber that balances the vacuum in the first chamber when the movable member is advanced toward the first end of the body; and c) allows atmospheric pressure to enter the second chamber when opened; and an actuator configured to actuate the pressurizing mechanism to cause the movable member to move towards the first end of the body and forcing the plunger rod to move within the fluid container, the actuator being connected to a fluid dispensing end of the fluid container and being switchable between a first state in which fluid in the fluid container is prevented from flowing through the fluid dispensing end and a second state in which the fluid can flow through the fluid dispensing end.
