Abstract
A valve assembly for controlling the application of suction and counterblow air to a blank mould of a glassware forming machine. The assembly comprises a body (1, 2, 3, 4) in which are enclosed a first valve (5) for controlling the application of suction, a second valve (6) for controlling the flow of counterblow air, and a third valve (7) for venting the blank mould. The body (1, 2, 3, 4) has a central chamber (32) through which the suction is applied when the first valve (5) is open, through which the counterblow air passes when the second valve (6) is open, and through which the mould is vented when the third valve (7) is open.
