<p>High-pressure washing liquid spray intended for use in a washing machine for ophthalmic glass or other substrates, consisting of an entry opening ( 11 ) for washing liquid and an exit opening ( 12 ) for liquid in a jet, connected by a channel. The channel ( 1 ) has a rectangular channel in cross section which introduces a constriction, in particular in the center, giving that channel an X shape, so as to form, on one hand, downstream of the above-mentioned constriction, an expanded exit cavity ( 13 ) ending in a slit forming the exit opening ( 12 ) and, upstream of the above-mentioned constriction on the other hand, an entry cavity ( 14 ) in the base cone where the rectangular base forms the entry opening ( 11 ) of the channel ( 1 ).</p> |
