ABSTRACT:
A pneumatic switch having a wiper seal to inhibit material from escaping from a pneumatic conveying line during a switching process and to maintain the pneumatic conveying line in a closed condition to prevent contamination of the contents of the pneumatic conveying line and an inflatable seal to seal around a pneumatic conveying line with the pneumatic switch including a movable housing that is moveable with respect to a second pneumatic conveying line. The movable housing bearing is carried by a movable plate that allows one to position or reposition the pneumatic conveying line with respect to another conveying line to thereby divert material from one conveying line to another conveying line while an inflatable seal allows one to seal and reseal around the pneumatic conveying line. A drive mechanism with preset stops allows one to position or reposition the pneumatic conveying lines with respect to one another and a pneumatic bearing purge system inhibits the pneumatic switch from being jammed during the switching process.
