Patent number: 9260286Abstract: A nozzle for dispensing fluid including a nozzle body having a fluid path through which fluid to be dispensed is configured to flow. The nozzle includes a main fluid valve positioned in the fluid path to control the flow of fluid therethrough, and a secondary fluid valve positioned in the fluid path to control the flow of fluid therethrough. The secondary fluid valve includes a secondary valve body and a secondary valve seat, the secondary valve body being movable between a closed position, wherein the secondary valve body sealingly engages the secondary valve seat, and an open position wherein the secondary valve body is spaced away from the secondary valve seat. The nozzle further includes an actuator operatively coupled to the main and secondary fluid valves.
