Abstract
In a proportional valve assembly, particularly for supplying compressed air on a glassware molding machine, a tubular body, having an axis and air inlet and outlet ports, houses a slide member which is slid axially along the axis, to open and close the inlet and outlet ports, by a linear actuator, on the one hand, and, on the other, by the reaction exerted by an elastic body and the compressed air; the elastic body being spaced apart from the slide member and connected to the slide member by a relatively moving device.
