Claim 0:
1. A spray device, for spraying a liquid microjet spray, comprising a spray nozzle unit, said spray nozzle unit comprising at least one spray nozzle having a chamber for receiving a pressurized liquid therein and having a perforated nozzle wall for releasing a microjet spray of said liquid, wherein said spray nozzle is formed by a nozzle body, comprising a support body with a cavity that opens at a main surface of said support body, said support body being covered by a membrane layer at said main surface and said membrane layer being provided with at least one nozzle orifice throughout a thickness of said membrane layer at an area of said cavity to form a nozzle membrane that is in liquid communication with said cavity wherein said at least one nozzle orifice comprises at least one deflecting nozzle orifice, releasing said microjet under a deflected angle along a jet line that is directed away from an imaginary transverse center line of said deflecting nozzle orifice, and wherein said deflecting nozzle orifice is in open communication with a liquid flow channel that has a lateral asymmetrical flow profile in terms of a liquid flow resistance from said cavity towards said nozzle orifice.
