Filed: 1993-12-10
Abstract: PURPOSE: To intermittently restore a processing wall to a state necessary for efficient operation by forming the processing wall as a part of the boundary of a continuous reentrant lumen and circulating wall conditioning shuttle along this lumen, thereby removing accumulated material. CONSTITUTION: When the circulating shuttle 25 completes the stroke by passing a long flow passage 22, the shuttle 24 existing thus far in a short flow passage 23 is pushed out into the long flow passage 22 of the lumen 12 and the previously freely moving shuttle 25 is positioned in the short flow passage 23 in a return portion 19. The vanes of the shuttle 25 are so deformed as to enter the constricted portion and are thereafter spread as a detent to the backward progression of the shuttle 25. The shuttle 24 which is freshly made free circulates by passing the long flow passage 22, by which the processing wall 26 is conditioned. On the other hand, the stopped shuttle 25 shuts off flow of the fluid passing the short flow passage 23. One of the two shuttles shuts off the flow passage 23 and the other shuttle conditions the processing wall 26 by passing the flow passage 22.
