ROTOR-TYPE HIGH-SPEED HYDRAULIC PULSATOR Russian patent published in 1999 - IPC

FIELD: obtaining pressure pulse; main units of vibration hydraulic pulsating equipment. SUBSTANCE: rotor with rollers or plates is mounted in housing on cantilever support. During rotation of rotor and contactors mounted in recesses of housing, liquid enters working cavities through suction hole; liquid is delivered to respective actuating mechanism for forming pressure pulse at moment when teeth of contactors are thrown into engagement with toothed quadrant. Synchronization mechanism ensure synchronous rotation of contactors and rotor. Rotor is sealed both in radial and axial direction. Synchronization mechanism is made in form of toothed fork integral with support of rotor and toothed quadrants mounted in recesses of rotor. EFFECT: high speed of rotor; increased frequency and power. 4 cl, 4 dwg
