Jet-generation apparatus and method for generating a liquid jet

Abstract

A jet-generation apparatus (100) adapted to generate a liquid jet (1), includes vacuum chamber (10), nozzle device (20) with at least one nozzle (21, 22), which is arranged for discharging liquid into vacuum chamber (10) and for generation of liquid jet (1), liquid supply device (30) including liquid reservoir (31) and first pump (32) and is coupled to nozzle device (20), collecting device (40) including collecting vessel (41) with inlet opening (42), which is arranged for collecting liquid jet (1) in vacuum chamber (10), and recovery device (50) arranged for recovery of the collected liquid from collecting vessel, wherein recovery device (50) includes second pump (52) arranged between collecting vessel (41) and liquid reservoir (31) and is adapted for the transport of the collected liquid directly into liquid supply device (30). A method for generating a liquid jet (1) with the jet-generation apparatus (100) is also described.
