ABSTRACT:
A pipe switch of the type having a stationary cylindrical housing enclosing a rotary cylindrical plug. The housing has a feeding connection for receiving pulverized or granular material and juxtaposed two discharging connections. The plug is formed with two diametral channels extending side-by-side so that in respective switching positions of the plug one of the channels connects the feeding connection to one of the discharging connections. The outlets and the inlets of the channels are surrounded by continuous sealing straps in such a manner that the distance in circumferential direction from the sealing strap and the adjoining side of the inlet or outlet openings is larger than the breadth of the inlet or outlet openings so that the sealing straps do not cross the edges of the mouth of the feeding and discharging connection pieces in the housing.
