Abstract
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).
