ABSTRACT:
A centering device provided with cleaning elements for cleaning a movable centering rod, and for preventing infiltration of dirt. The cleaning elements comprise at least one annularly-shaped scraping member provided with angularly spaced apart cross-cuts, which divide the scraping member into circular sections having inner scraping edges. The scraping member is locked against a conical shoulder in such a way as to be elastically yieldable, making the inner scraping edges of the sections adhere to the centering rod.
