ABSTRACT:
An inflation valve includes a hollow sleeve having a first chamber and a second chamber; a first valve body located in the first chamber; a second valve body located in the second chamber; an air inlet connector screwed to an upper end of the second chamber; and a central pin assembly mounted in the air inlet connector. When an object being inflated by the inflation valve is excessively inflated, the inflation valve automatically releases surplus high-pressure air via at least one release pod of the second chamber by pushing the first valve body and the second valve body upward.
