DIAPHRAGM Russian patent published in 2006 - IPC F04B43/00 F16J3/02 

FIELD: transfer systems.

SUBSTANCE: invention relates to designing and operation of units of transfer systems where liquid component is oil-and fuel-oil containing products. Diaphragm is made in form of rubberized fabric flexible plate and is provided with mounting holes over periphery and reinforcement members. The latter are formed by coaxially arranged ring bodies and/or elastic segment plates installed with clearance in between. Reinforcement members are essentially balls arranged over concentric circles in layer of rubberized fabric base. Said members can be made in form of round corrugated envelope with fitted-in intersecting axles.

EFFECT: increased operating capabilities of multicyclic load units when handling liquids at pressures from 0.2 to 20 Mps and higher in which proposed diaphragms are used.
