Abstract
A pneumatic servo system which has a storage tank filled to a predetermined ressure with an inert gas such as nitrogen that is heated by a heat squib device to raise the temperature of the gas and also to increase the pressure of the gas in the storage tank and be supplied through an explosive actuated frangible valve to a pressure regulator for regulating an outlet pressure to a servo valve for controlling flow to and from a pneumatic motor.
Claims5
A pneumatic servo system comprising a container filled with inert gas, a heat squib mounted on the side of said container for heating the inert gas and increasing the pressure thereof when the heat squib has been ignited, an outlet from said container, control means connected to said outlet from said container a pressure regulator having an inlet, said control means including a piston actuated explosive valve interconnecting the outlet from said container to said inlet of said pressure regulator, a manifold outlet, and said pressure regulator being connected to said manifold outlet for delivering said inert gas to said manifold outlet at a predetermined pressure.
