APPARATUS FOR MECHANICALLY CLEANING INNER SURFACE OF ARTICLE CAVITIES

摘要

FIELD: cleaning inner surfaces of cavities of parts and aggregates such as pipelines with different shape of their cross sections. SUBSTANCE: apparatus includes housing having inner duct for feeding working fluid at least with one through opening and at least with one outer closed groove for placing cleaning bodies. Inner duct of housing is communicated with environment by means of through opening. Cleaning bodies are freely arranged in closed groove. Maximum gap between housing and surface of article is less than minimum dimension of any of cleaning bodies. Through opening is provided on inner surface of walls of closed groove and it is inclined relative to line normal to said surface. EFFECT: simplified design, enhanced efficiency, elarged functional possibilities of apparatus, high quality of cleaning, increased useful life period of apparatus. 7 cl, 2 dwg
