Toy Water Rocket Launcher

Abstract

A toy rocket launcher to launch a liquid jet propelled rocket by means of air pressure developed from a pressurized liquid source. The invention utilizes a pressure tank, which is filled with liquid from a pressurized source such as a garden hose, thereby displacing the air in the tank and forcing it up into the rocket creating pressurized air in the rocket for propulsion purposes.

1 . A pressure tank that is used to launch a toy liquid/air rocket by displacing the air in the tank with pressurized liquid entering the tank through an inlet at the bottom of the tank and forcing the air and liquid to be compressed up into the rocket through a launch tube at the top of the tank.  
   
   
       2 . A drain valve at the bottom of the tank in  claim 1 , to empty the liquid and allow air to enter the tank for subsequent launches.  
   
   
       3 . A variable height spout on the drain valve of  claim 2  to control the amount of water/air remaining in the tank after the water is drained.
