Abstract
Apparatus for deflecting a high pressure jet of liquid, comprising the provision of a pair of sharp edged deflecting members secured to a nozzle member in a position such that the sharp edges of the deflecting members protrude into the jet of liquid to shape the jet to the required form. The provision of sharp edged deflecting members obviates the necessity for complex nozzle forms. The relatively simple shape of the deflecting members permits their formation from a hard material by machining or the like in an economical manner.
Claims11
Apparatus for deflecting a high pressure jet of liquid, comprising:
- (a) a nozzle;
- (b) an orifice in said nozzle through which liquid may pass to form said jet;
- (c) said orifice having an inlet end for liquid and an outlet end;
- (d) a pair of deflecting members, each of said deflecting members having an inlet-end facing surface and an outlet-end facing surface, said outlet-end facing surface being configured to form a chisel shaped end region of said deflecting member, which region terminates in a sharp edge;
- (e) mounting means enabling mounting of said deflecting members relative to said outlet end of said nozzle;
- (f) the deflecting members being positioned in a jet deflecting position by said mounting means so they are diametrically opposed to each other and so that a portion of each said chisel shaped end region projects into the path of said jet, each said outlet-end facing surface being inclined away from said sharp edge to prevent said jet, as it passes through a restrictive aperture formed by the opposed sharp edges, from adhering, by capillary action, to said deflecting member;
- and
- (g) securing means for firmly securing each deflecting member relative to said nozzle in said jet deflecting position.
