ABSTRACT:
An apparatus and a method are indicated for a paper-making machine, for delivering liquid from a first level in a first space, through a line into a second space on a second, higher level, under the action of a difference in the gas pressures over the liquid in the first space and in the second space. A throttle valve in the line is controlled, to regulate the fluid flow, in such a way that the throttle valve is at least partly closed when the gas flow through the line rises, and is opened when there is little gas flow through the line. This guarantees continuous delivery of liquid, stable flow conditions prevail, and a delivery that is largely free of pulsation is achieved with a low proportion of gas (FIG. 2).
