Fluid dispensing unit having a circulation system and a method for circulating a fluid in a fluid dispensing unit

A hose and nozzle assembly for use with a fuel dispenser, comprising:

• an elongate tube having first and second pathways extending therethrough between first and second ends thereof, the first end of the elongate tube being configured to couple to a pump for receiving fluid from a fluid reservoir;
• a nozzle coupled to the second end of the elongate tube and configured to deliver fluid to a vehicle;
• and
• a valve having
• an open state in which fluid flowing through the first pathway can flow through and exit the nozzle to be delivered to a vehicle, and
• a closed state in which fluid flowing through the first pathway is prevented from exiting the nozzle;
• wherein:
• in response to the valve moving to the closed state, the fluid is directed through the second pathway to flow back toward the first end of the elongate tube;
• with the valve in the open state and with the valve in the closed state, the fluid flows from a first open end of the first pathway and toward a second open end of the first pathway;
• first and second open ends of the first pathway are each on a downstream side of the pump and a downstream side of the fluid reservoir;
• with the valve in the closed state, the fluid flows out of the second open end of the first pathway and into a first end of the second pathway and in the second pathway toward a second open end of the second pathway;
• and
• the first open end of the second pathway is on the downstream side of the pump and the downstream side of the fluid reservoir, and the second open end of the second pathway is on an upstream, suction side of the pump and the downstream side of the fluid reservoir.
