A viscous fluid pressure-feed apparatus which feeds and drains a slurry of a highly viscous fluid in a casing to a filter press, or the like inside, or outside, an elastic film by pressurizing the elastic film through the feed/drain operation by an oil pressure generation apparatus outside, or inside, the elastic film which is supported by the casing. Particularly, a mechanical press-in apparatus such as a screw feeder is disposed at a suction port of the viscous fluid into the elastic film disposed in the casing so as to operate in synchronism with expansion and contraction of the flexible film and to compulsorily supply the slurry having a high viscosity from a slurry tank. Furthermore, a gas reservoir chamber is added to the casing and a gas exhaust valve is disposed in the gas reservoir chamber. The interior of the casing is sealed through a valve disposed at an outflow port of the press-in apparatus and separation and exhaust of the gas existing in mixture in the slurry of the viscous fluid can be made freely through the opening or closing operation of the exhaust valve. Thus, the pressure-feed apparatus of a viscous fluid of the invention can make high pressure pressure-feed of the viscous fluid.
