摘要： A device for generating an underpressure comprising an ejector unit (1), and a thereto connected pressurised air channel (2), which over a (first) pilot valve (3) is connected to an ejector (4), which is arranged inside the ejector unit (1), control channels to the pilot valve and an underpressure channel (20), which is connected to the suction side (17) of the ejector. The invention is distinguished by the ejector unit (1) on one side (8) being provided with an adaptation surface which is constructed so as to be sealingly mounted on a manifold (10) for valve mounting, whereby the same hole pattern is used as for the valve units for the manifold in question and for that purpose is provided with at least one port which is located such that at least pressurised air supply is provided through a channel (2) in the valve manifold (10). The invention also concerns a manifold arrangement including a device for generating an underpressure.
