Abstract

PURPOSE: To accomplish an efficient supply of liquid with a pump discharge pressure kept at a set level by controlling the revolutions of the engine related to a pump discharge pressure.
CONSTITUTION: A pump 2 is driven with an engine 1 to feed a liquid in a tank 3 to a feed hose 6 by way of a discharge tube 4. When the liquid is high in the viscosity and long in the supply distance, a part of the liquid is recirculated to a pump suction section through a relief valve 20 as the pump discharge pressure exceeds the set pressure. Under such a supply condition, a pump discharge pressure works on the rear surface of a piston of the second cylinder 17 by way a piping 19 so that a piston rod changes a change-over valve 14 to the right position against the force of a spring 18, allowing a liquid discharged from a pump 2 to flow into a tip chamber of the first cylinder through a branch pipe 15 thereby reducing the first cylinde 12. A control lever 7 is pulled back to lower the revolutions of the engine resulting in lowering in the discharge pressure.
