Abstract
A check valve according to some embodiments of the disclosure includes a body forming a cavity and which defines an entrance opening, a wall extending from the body at an end opposite to the entrance opening, and rare-earth magnets attached to the wall. The body and wall are formed of a flexible and resilient material. The wall includes elongated wall portions joined together by end portions and a passageway extending from the cavity to a slit at the end of the wall. Interior surfaces of the wall portions abut against each other in an at rest condition, and the interior surfaces of the wall portions are separated from each other in a flow permitting condition such that the passageway is opened. The attractive force generated by the magnets cause the wall portions to move to the at rest condition.
