Abstract
A pipe switch for pneumatically conveying a material such as bulk material includes a housing provided with a first port, a second port extending coaxially with the first port and a third port having an axis extending at an angle of less than 90.degree. relative to the axis of the second port, with the housing accommodating a cock which extends between opposing side covers and by which the first port is selectively connectable with the second port and with the third port. In order to reduce a danger of accident and to allow easy access to the interior of the pipe switch, the entire drive unit for actuating the cock is connected to the pipe switch at one of the side covers, with all movable parts being housed within an external compartment defined by an outer wall mounted to the one side cover.
