Abstract:
A inflation valve comprising:a valve housing having an inner wall, a cylindrical inner chamber terminating in a gas outlet, and a gas inlet bore providing fluid communication between said inner chamber and a pressurized gas source; a piston enclosed in said inner chamber, said piston comprising at one end a head directed toward said gas outlet and at the opposite end a valve actuator connector, said piston further comprising a gas inlet seal positioned between said head and said actuator connector, said seal releasably sealing said gas inlet bore from said gas outlet when said piston is in a normal non-actuated position, said piston further comprising first and second interconnecting components, said first and second piston components being interconnected by corresponding flanges on said components; a valve actuator connected to said actuator connector, said actuator operating to pull said piston, thereby moving said gas inlet seal away from said gas inlet bore and putting said inner chamber in fluid communication with said gas inlet bore and said pressurized gas source, and at least one regulating spring confined within the portion of said inner chamber proximate said actuator connector, said spring being compressible by the force of pressure exerted by gas introduced through said gas inlet bore into said inner chamber when said valve actuator and actuator connector are actuated to pull said piston towards said spring, said piston returning towards its normal non-actuated position as gas contained within said inner chamber exits via said gas outlet.
