METHOD AND DEVICE FOR DEGASSING OF DISCHARGE PRESSURE OF DOSING PUMP Russian patent published in 2013 - IPC F04B53/06 F04B13/00 

FIELD: engines and pumps.

SUBSTANCE: degassing method of discharge space (1) of a dosing pump involves pulse supply. Gas bubbles occurring in discharge space (1) owing to fluid medium that forms gas and adhesive to inner surfaces are separated from those surfaces. Gas bubbles (4, 4', 8, 8') present in discharge space (1) are collected; movement is performed in direction of discharge valve (6), and on the side of discharge valve (6), which faces the discharge space, there formed is collecting gas bubble (7). Owing to increasing the pressure, collecting gas bubble (7) standing at discharge valve (6) laves discharge space (1) in the form of outlet gas bubbles (7') to the discharge pipeline. A dosing pump includes a pulse supply device located in discharge space.

EFFECT: improving startup characteristics of dosing pumps.
