Abstract
A plurality of distributing pipes arranged in a circular pattern around a central pipe are selectively interconnected with the central pipe by a rotary pipe switch which includes a pipe elbow having a rotary joint at one end thereof connecting the elbow to the central pipe to enable rotary motion of the elbow relative to the central pipe and an axial compensator at the other end of the elbow with a connector attached to the axial compensator for effecting connection and disconnection of the other end of the elbow with each of the plurality of distributing pipes. A driving device is provided to effect compression and expansion of the axial compensator in order to effect selective connection and disconnection of the connector with the various distributing pipes.
