Title:
METHOD OF MAKING WINDOWS IN PARTS OF THE DISTRIBUTING DEVICE OF A POSITIVE-DISPLACEMENT HYDRAULIC MACHINE
Document Type and Number:
WIPO Patent Application WO/1982/000682
Kind Code:
A1
Abstract:
A method of making windows in parts of the distributing device of a positive-displacement hydraulic machine consists in clinching technological projections (2) formed between channels (3) made in the parts, so as to close the channels (3) on their buttend side and in subsequently making windows (4) of a desired configuration, the width of each window (4) being less than the diameter of the corresponding channel (3) and the area of each window (4) being commensurable with the area of its channel (3).
