Abstract
A device for generating an negative pressure comprises a plurality of ejectors and a receiving device therefor. The receiving device comprises at least one connection for a compressed air line, the connection protruding into a compressed air distribution system to which a compressed air channel of each ejector can be connected, and each ejector being provided with an negative pressure channel that can be connected to the negative pressure system of the ejector. The receiving device forms a holding frame and a quick-change system for the ejectors, and can be connected to the ejectors by means of control lines, and to a machine control system.
