Abstract
An ejector unit (1) is mounted on a conventional valve manifold (10) with a manifold pressurised air supply connected to an ejector (4) through channels (15, 16) and a first pilot valve (3). A suction channel (20) and a return air channel (22) are connected through manifold (10) to outlet ports from the ejector (4) suction chamber (17) and outlet nozzle (18') respectively. The ejector unit (1) is mounted through face (8) onto manifold (10) using the same hole pattern as for valves connected to the manifold.
