Patent number: 4417596Abstract: A filter-cleaning apparatus comprises a hollow, elongate body provided with cleaning fluid inlet and exit means at respective ends thereof. The cleaning fluid inlet means comprises an annulus which extends peripherally around one end of the hollow body and which defines together with the outer wall of the hollow body a space for receiving cleansing fluid from a source of such fluid. The interior of the hollow body communicates with the space defined by the annulus through a series if holes formed in that part of the wall of the body located within the confines of the space. When cleaning a filter, the filter is inserted into the hollow body through the inlet means herefore and the source of cleaning fluid activated. The filter is then moved axially in the hollow body, past the series of holes, until all the filter has been cleaned. A closure means is provided at the cleaning fluid inlet, to prevent the escape of cleaning fluid during operation.Type: GrantFiled: September 10, 1981Date of Patent: November 29, 1983Inventor: Bo Pahlen
