Abstract
Improvements in the construction of switching valves for the alternative communication of a consumer with air overpressure or air vacuum, preferably in each case with a junction for the air overpressure, the air gap and towards the consumer, characterized in that the force of a spring, directed opposite the junction for the air overpressure, acts a piston slidingly arranged in the valve casing, as well as through it, on a closing part, the force of the spring being greater than the force on the piston, corresponding to the pressure difference between the air vacuum, and atmospheric pressure, but is less than the force corresponding to the air overpressure on the piston.
