ABSTRACT:
A vacuum-control valve for milking systems, with a valve body that is positioned upright and moves axially inside a housing and has a conical projection extending into an air-intake, with the valve-body cross-section changing as it moves axially, whereby the air-intake communicates with a vacuumized line. An aerodynamic structure is positioned under the valve body and is connected to the valve body by way of a rod such that the air entering the air intake exerts a downward force on the valve body.
