Patent FR-2285927-A1 (FR)
IPC: B60S1/52
Filed: 1975-09-26
Abstract: In the method, for example water is passed into a flow guide chamber (13). Some of the water flows along the side walls (15, 16) of the chamber (13) back into this and cause vortexes on both sides of the main stream. As a result of small asymmetries, the vortexes unite and force the mainstream against a side wall (16). As a result, the static pressure in the chamber (13) increases, so that water is forced via the side channels (21, 22) into the outlet region (17). The jet flows past one outlet orifice (23), as a result of which the pressure decreases in the channel (21) and its inlet orifice (24). This effects a deflection of the jet to the other outlet orifice (25), where the process described is repeated. The jet is swung to and fro by self-induced pressure variations at the inlet orifices (24, 26). By means of the method, an oscillating spray jet with predetermined drop size and distribution can be generated with considerably lower pressures than hitherto. The method can be carried out with an extremely compact apparatus without moving parts. The apparatus can be designed inter alia as a spray head, for example for cosmetic equipment.
