Making the world better, one answer at a time. A vacuum breaker is a mechnical device used to avoid backflow or a negative pressure in a plumbing system. It typically consists of an air valve with a spring holding it closed. When the pressure within the system is positive, the valve remains closed. In a vacuum breaker the moving contact and fixed contact are sealed inside a vacuum chamber. Electrons cannot flow in a vacuum, therefore as soon as the moving contact s â¦ eperates from the fixed contact the arc meets an infinite resistance and is immediately extinguished.
