ABSTRACT:
Anti-spray fluid dispensing nozzle for filling an open top container. The nozzle comprises an elongated fluid supply conduit establishing a fluid path between a source of pressurized fluid and the container to be filled. First and second valves are mounted in the supply conduit disposed in a spaced apart relationship with the first valve positioned upstream the second valve. Each valve includes a movable closure member cooperating with a valve seat to control the flow of fluid through the supply conduit. The closure members of both valves are coupled to a common actuating rod mounted for linear movement within the supply conduit to selectively displace each closure member between a valve closed position and a valve opened position. The closure member of the first valve is capable of sliding movement on the actuating rod, permitting the closure members to engage their respective valve seats while moving toward valve closed positions at different instants in time, thereby reducing the fluid pressure differential across the second valve when the latter closes for preventing a fluid spray to occur.
