Attorney, Agent or FirmInternational ClassA63H 029/10AbstractA rocket launcher (18) is disclosed having a pressure chamber (74) coupled to a pump (66) through a pressure tube (67) and a release valve assembly (87) having a manifold (78) in fluid communication with the pressure chamber. The manifold has a plunger (79) therein which is slidable between a first position storing pressurized air within the pressure chamber and a second position releasing pressurized air from the pressure chamber and into a launch tube (76).Field of SearchFrom rocket or simulated rocketOPERATED BY RELATIVELY MOVING FLUID OR PRESSURE DIFFERENTIAL DISCRETE LAUNCHER, ACCELERATOR, OR RETARDER FOR TOY VEHICLE Provided by movement of user-actuated, projector-mounted pressure member By plunger moving within cylinder To store pressure in valved container With check valve permitting recharge, and control valve for discharge, of fluid pressure By valve means | |
