FIELD: fluid delivery systems.

SUBSTANCE: group of invention relates to a system for delivering fluid to an animal and to a method for delivering fluid to an animal using said system. The system for delivering fluid to an animal comprises a reservoir with a volume for fluid, a delivery outlet, a valve with fluid communication between the reservoir and the delivery outlet. The valve has an inlet for receiving fluid from the reservoir, a first outlet in fluid communication with the delivery outlet, and a second outlet in fluid communication with the reservoir via a reservoir return pipe. The system also includes a control means for opening and closing the first and second outlets of the valve and a pump for continuously pumping fluid from the reservoir to the valve and from the valve through the reservoir return line to the reservoir. This said, when the control means opens the first valve outlet and closes the second valve outlet, fluid flows from the reservoir to the delivery outlet, and when the control means closes the first valve outlet and opens the second valve outlet, fluid flows through the return pipe reservoir to the reservoir.

EFFECT: allowing the substance to remain suspended in solution when the system is active or when it is at rest, and also that the spray head does not require preparation after each interruption in the process.
