Abstract: Means adapted to receive a supply of compressed air and discharge the compressed air therefrom in a regulated manner via a selected port therein, control means within the means, for use in diverting the flow of the supply of compressed air within the means to thereby divert the air from the selected port to a further port in the means, whereby at least a partial vacuum condition is created in the selected port, allowing the ingress of air therethrough from without the means, the ingressed air mixing with the diverted air so as to be discharged through the further port.
