A launching chamber (20) with an exhaust orifice (32) covered by an obstruction member (34, 36) is in fluid-pressure dependent mechanical communication with an equilibrium chamber (40) such that when the two chambers are in fluid pressure equilibrium and fluid pressure in the equilibrium chamber is decreased to a predetermined amount less than the fluid pressure in the launching chamber the obstruction member uncovers the exhaust orifice. The equilibrium chamber (40) is vented through a turbine tube (70) which drives a turbine wheel (72).

[ What is claimed is:] [1.] A launcher for a toy projectile or similar launchable object comprising:a launching chamber having an exhaust orifice and a first fluid-flow mechanism for receiving fluid into said launching chamber;an obstruction member having a head portion, said obstruction member in mechanical communication with said launching chamber such that said head portion is reciprocally positionable over said exhaust orifice;an equilibrium chamber having a second mechanism for fluid communication therewith, said equilibrium chamber in pressure-depending variable mechanical communication with said launching chamber and said obstruction member such that when said launching chamber and said equilibrium chamber are placed in a condition of fluid pressure equilibrium through application of fluid under pressure to said first fluid-flow mechanism and said second fluid-flow mechanism said head of said obstruction member obstructs said exhaust orifice of said launching chamber and then when the fluid pressure in said equilibrium chamber is decreased to a predetermined amount said head of said obstruction member uncovers said exhaust orifice; anda vent mechanism in selective fluid-flow communication with said second fluid-flow mechanism so that said equilibrium chamber may be vented therethrough.
