摘要

The injector device (100) has a housing (10) with the outlet of a pressure air jet projecting into it, a supplementary jet element (30), an injector jet (33) and a jet hose (50). A relief jet (20) is fitted between the outlet of the injector jet and the end of the jet hose. This jet has a truncated-cone relief jet boring (21) for at least part of its length, which widens from the cross section of the jet boring (32) to that of the hose channel recess (51).
