Cleaning device with jet at end of liquid central channel - has jet-shaft passing contact free through hollow rotor to adjustable eccentric head describing conical surface during oscillatory motion
Cleaning device with jet at end of liquid central channel - has jet-shaft passing contact free through hollow rotor to adjustable eccentric head describing conical surface during oscillatory motion
The cleaning device (10) has a liquid jet (27) movable on a circular path at the outer end of the liquid central channel (26) passing through the jet-shaft (25). The rotary-rigid jet-shaft (25) describes a conical surface during its oscillatory motion, with the apex at the jet-shaft end and the basis at the jet (27). The jet-shaft (25) is coupled with the driving motor (19,21) through the rotating and adjustable eccentric head (24). It passes contact free through the hollow rotor (21) and is connected to a high pressure pipe (32). The hollow rotor (21) is mounted clearance free and tipping secure on ball- or roller-bearings (22,23). USE/ADVANTAGE - Cleaning device of compact design and small rotating mass.
