FLUID MATERIAL FEEDER Russian patent published in 2004 - IPC

FIELD: mechanical engineering; lubricating material feeders. SUBSTANCE: proposed device contains housing with inlet and outlet branch pipes, and chamber made of elastic material filled with fluid material, and perforated element. Elastic material chamber is installed in housing to form space for gas. Perforated element is installed inside chamber to pass fluid material out of chamber. End face of perforated element is connected with outlet branch pipe, and gas space is isolated from fluid materials space in chamber. Gas pressure source is connected with device through throttling element. Perforated element can be made flexible, or in form of spring, and housing with outlet branch pipe can be made flexible. Efficiency of device is 95%. EFFECT: provision of reliable feeding of fluid materials of different density with viscosity of 2.2-1500 sq.mm/s. 5 cl, 1 dwg
