HYDROPULSATOR WITH OFF-LOADED ROTOR Russian patent published in 1999 - IPC

FIELD: vibration-process technology. SUBSTANCE: volume hydropulsator has case, closers, and rotor provided with channel communicating with high-pressure sections of working-liquid cavity. Rotor blades have packing rollers and packing teeth contacting closer teeth. Tight contact in packing teeth is ensured due to tooth-to-tooth play in synchronizing gear members. Liquid flow pulsation frequency built up by volume hydropulsator equals rotor shaft rotational frequency multiplied by number of rotor blades. EFFECT: improved efficiency due to rotor off-loading and adequate packing. 3 cl, 3 dwg
