Abstract (en)

Backwashing is used for easily eliminating clogging of a nozzle member (9). In high-pressure jetting, an inflow piping is connected with a first channel opening (10) and an outflow piping is connected with a fourth channel opening (12) to draw in pressurized fluid through the first opening first (10) toward the fourth channel opening (12). In backwashing, the inflow piping is connected with the fourth channel opening (12) and the outflow piping is connected with the first channel opening (10) to draw in pressurized fluid through the fourth channel opening (12) to the first channel opening (10), so as to expel material particles that are to clog a channel of a nozzle member.
