Abstract
PURPOSE:To prevent acting of an excessive force to a piston in an apparatus for conveying a highly viscous fluid like ready-mixed concrete under high pressure, by dividing the inner space of a cylinder into a chamber for a fluid to be conveyed and a chamber for a driving liquid. CONSTITUTION:When liquid is forced into a cylinder 3 by a liquid pump 7, a piston 6 is urged by the liquid to force out a substance to be conveyed that has been introduced into a chamber 4 for the substance to be conveyed. That is, since the piston 6 is acted at one side thereof by pressure of the substance to be conveyed in the chamber 4 and at the other side by pressure of liquid in a driving liquid chamber and the above two pressure are almost equal to each other, differential pressure acting on the piston is considerably small, so that no excessive local load does not act on the piston 6. Further, since pressure in the chamber 5 is increased with increasing of the discharge pressure of the pump, differential pressure acting on the piston 6 is not changed substantially even if the discharge pressure of the pump is increased considerably.
