ABSTRACT:
An inflation valve includes a main valve body having an outlet port, a rupture port, and a pull cord retainer. A puncture retainer body secures a puncture disc within the main valve body to seal the outlet port to gas flow. A slot in the puncture retaining body permits gas flow to the outlet port. A puncture pin received within the puncture retaining body includes a center bore permitting gas flow to the outlet port. A rupture disc breaks under high pressure conditions to permit pressurized gas to exit the rupture port. The rupture disc and puncture disc are interchangeable. A release assembly associated with the pull cord retainer permits manual release of the puncture pin. A vacuum washer is sealed between a vacuum retainer and the pull cord retainer to prevent gas from exiting the pull cord retainer when the inflation valve is activated under vacuum.
