Abstract
The present disclosure relates to a three-function check valve that in one embodiment is attached to a vacuum bladder full of media (foam beads). This three-function check valve is comprised of a selection piece, silicone membrane, and a mounting base all in one sub-assembly. Furthermore, this valve has three positions with three distinct functions. These functions are to create an airtight seal, allow for free flow in and out of the bladder, and restrict flow of air based on a differential pressure.
