Abstract (en)
[origin: EP0872647A2] The invention is directed to a vacuum control and cutoff apparatus for a pneumatic duct (2) connecting a vacuum generator and a vacuum user device to each other. The apparatus is constituted by a closure member (11) of the duct (2), controlled by a fluid under pressure whose flow is in turn controlled by an interception member (5) which is operated by the vacuum amount within the duct (2). The interception member (5) switches over the state of a signalling device (14) which may transmit to other apparatuses the information related to the vacuum condition of the devices connected to the duct (2). <IMAGE>
