BATCHER FOR LIQUIDS Russian patent published in 1995 - IPC

FIELD: measuring equipment. SUBSTANCE: batcher comprises tanks 1 for different liquid components, measuring chambers 2, and driving mechanism 3. The measuring chamber is coupled with the tank 1 through inlet opening 4 which is overlapped with plate valving member 6 of the intake valve rigidly connected with piping rod 5 whose end is provided with shackle 7. Valving plate member 13 of the intake valve is also rigidly connected with rod 14 provided with spring 16 which transmits an effort of pressing to the intake and outlet valves. Bushing 12, which is used for control of flow rate, is positioned within the chamber and passes through its bottom. When lever 20 of a drive of vertical displacement moves up through shackle 7, the outlet valve is pressed to the bottom of drain branch pipe 11, intake valve is opened and measuring chamber 2 is filled with liquid. Air is discharged through pipe 5. In moving downward lever 20 presses rod 14, the outlet valve is opened and the intake valve is closed. Portion of drained liquid is determined by position of the top face of bushing 12. EFFECT: enhanced accuracy. 2 dwg
