PASTY MASS TRANSPORTATION METHOD, AND PUMPING UNIT FOR PASTY MASS TRANSPORTATION Russian patent published in 2013 - IPC F04B15/02 F04B7/00 

FIELD: engines and pumps.

SUBSTANCE: each cylinder is connected through an inlet opening closed with its associated inlet damper to a prefill tank. Each cylinder is connected through an outlet opening closed with its associated outlet damper to a transportation pipeline, in which pasty mass is transported from the prefill tank to the appropriate tank during cylinder suction stroke at the open inlet opening and the closed outlet opening, and pasty mass is transported to a transportation pipeline during cylinder discharge stroke at the open outlet opening and the closed inlet opening. A piston speed during suction stroke is higher than that during discharge stroke. At the end, near the end or immediately after the end of the suction stroke, the inlet opening is closed by means of the inlet damper; after that, pasty mass is compressed in the cylinder before the outlet opening is opened.

EFFECT: continuous uniform transportation of pasty mass and satisfactory sealing of the inlet opening is provided.
