AUTOMATIC PRESSURE VALVE FOR INFLATION / DEFLATION OF A PNEUMATIC ARRANGEMENT

An Automatic pressure valve for the inflation—deflation of pneumatic arrangements comprises a main body () with an inlet connector () communicated with a pressurized air supply network an outlet connector connected to a pneumatic arrangement and a mechanical means which allows for a total or partial air passage or blockage to perform inflation—deflation operations of the pneumatic arrangement in a faster and practical way. The mechanical means comprises a main movable plunger () having an inner stepped through channel (), a spring () arranged on a seat () defined in the inner stepped channel (), an inflation plunger () operatively retained by said spring (), a proximal movable end () within a first inner chamber (), a reduced middle section (), and a distal movable end () having a smaller diameter than the proximal end () and arranged within a second inner chamber ()
