Abstract
An air/water valve assembly for use in an endoscope or other medical equipment is provided. The valve assembly includes a spool and a one-piece sealing member that includes a number of sealing rings. The spool can be injection molded, and the sealing member can be overmolded onto the spool. A spring, retainer, and housing are also included to form the valve assembly. As such, an air/water valve assembly may be made that can be used in a single medical procedure and then discarded in a cost-effective manner. Corresponding methods of manufacturing an air/water valve assembly are also provided.
