A device at a high pressure spraying apparatus incorporating a liquid motor (6), which via a common shaft (5) drives a pump wheel (11), and where an entering liquid flow before the liquid motor (6), in a division chamber (2) is divided into a main flow, which passes through the liquid motor (6) and drives this, its shaft (5) and the pump wheel (11) connected thereto, and into a part flow, which is led to the pump wheel (11) and by this is given a high pressure and via a conduit (12) is supplied to a high pressure nozzle (13), whereby the main flow via a conduit (7) downstream of the liquid motor (6) is discharged to a low pressure nozzle (8) as a low pressure liquid for rinsing purposes. |
