Abstract:
A liquid filling nozzle comprising:a tubular nozzle main body with a liquid supply opening formed in a side wall thereof and a liquid discharge port formed in a lower end thereof, a center rod disposed inside said nozzle main body concentrically, a raising-and-lowering device which raises and lowers said center rod, and an opening-and-closing valve body which is provided at a lower end of said center rod and opens said liquid discharge port when said center rod is lowered and closes said liquid discharge port when said center rod is raised, so that a liquid that enters via said liquid supply opening flows out of said liquid discharge port through a flow path which is between an inside wall surface of said nozzle main body and an outer surface of said center rod; and said liquid filling nozzle further comprising: a throttle valve mechanism which is disposed in a position below said liquid supply opening inside said nozzle main body and constricts said flow path for said liquid, said throttle valve mechanism being comprised of: a throttle valve seat which is disposed on said inside wall surface of said nozzle main body, and a throttle valve body which is provided on said center rod, and wherein said throttle valve mechanism opens when said center rod is lowered, and, when said center rod is raised, said throttle valve mechanism closes before said opening-and-closing valve body closes off said liquid discharge port, thus constricting said flow path.
