Abstract
An air valve assembly includes a housing defining an internal channel configured to receive a first member, the first member is fluidly connected to an air source, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, and a sealing member positioned in the internal channel and defining a first inflation aperture, the plunger member slidably received by the first inflation aperture. In a first inflation configuration, the first member is configured to form a magnetic connection with the sealing member and contact the plunger member to overcome the biasing force, the plunger member is configured to responsively slide relative to the first inflation aperture to facilitate a flow of air between the sealing member and the plunger member.
