COANDA INJECTOR AND COMPRESSED GAS LINE FOR CONNECTING SAID INJECTOR

摘要

The present invention relates to a Coanda injector (1), especially for cleaning filter elements of dust-laden gas filters, comprising an inlet (3) for a medium (4) to be suctioned, a pre-chamber (5) having at least one inlet (6) for a pressurized medium (7) that is fed through a compressed gas line (2), in addition to a nozzle slot (8) preferably annular in shape and an outlet (9) for the medium (4) to be suctioned and for the pressurized medium (7). According to the invention, in order to enable an easy, space-saving, pressure loss reducing connection to a compressed gas line, the inlet(3) and the at least one inlet (6) of the pre-chamber (5) are essentially arranged on one plane so that the Coanda injector (1) can be directly connected to the compressed gas line (2) by the inlet (6) of the pre-chamber (5). The invention also relates to a compressed gas line (2) for connecting said Coanda injector (1), which is fitted with fluidic chamfers (17) in the connecting area of the inlet (6) of the pre-chamber (5).
