摘要

(54) An apparatus for supplying liquid to orotsschtoschey porodorazr toayuschemu instr nmentu mining machine; (57) A device for supplying scrubbing liquid to porodorazrshayusche gu mining machine tool comprises a housing, at least two channels for supplying air to the ejector chamber disposed in Corts insert and placed in front of the filter insert. The housing is formed with an ejection chamber jet forming chamber and the axial channel for supplying irrigating: fluid in the ejector chamber. The insert is located on its outer lateral surface grooves with a helical shape and tsentralnsh Kan, PDE oroschayuttsey for passage of fluid in jet forming chamber. The groove walls form with the housing communicating with the cavity jet forming chamber peripheral channel. Area peripheral channel cross-section is not less than 8, .5 times and not more than 9.9 times prevnpaet cross-sectional area of ​​the axial passage. The cross sectional area of ​​the axial passage is not less than 1.5 times and not more than 2.5 times the cross-sectional area of ​​the central Canada. of 15. l, f BACKGROUND 9 Fig. Referent; the application №; SHK 6 E21 F 5/02 E2I F 5/04; Summary B.
