Rotating scraper unit for separation of aqueous cooling medium, is clamped on bar that is away from spring arm, where arm`s outer side is strengthened by recess area that is opened so that accumulations deposited in it are washed up

摘要

The unit is clamped on a bar for separation of attachments joined to inner surfaces of a tube. The bar is led away at a distance from the center of an inner side of a round shaped spring arm. An outer side of the spring arm is strengthened by an inclined recess area and is thickened within an area of a fitting shoe. The recess area is broadly opened so that the accumulations deposited in it are washed up.
