Ink under pressure is introduced into a tubular sleeve (4) through a connecting pipe (21). A second pipe (22) connected to the sleeve (4) constitutes a purging circuit. The ink is filtered by a tangential filter (30) which also acts as a strut. The filter is made watertight to the sleeve (4) by expanding seals at top and bottom (13, 15). After passing through the filter the ink is moved to a nozzle (15,31) by a resonator located inside the filter. The resonator receives an electrical supply through a cable (23) secured by a flange (28). |
