摘要

Improvements in dosing devices designed to introduce adjustable quantities of liquids in a system of circulating liquids under pressure, whose introduction is in linear dependence with respect to the quantity of liquid that circulates through the apparatus, consisting of a drive device in the system of pressurized liquids for actuating a distribution device for the admission of a dosing pumping device, characterized in that in said liquid pressure system there is a device that causes a small pressure difference and a driving member which, depending on the amount of liquid that circulates, acts on a closing and distribution member of an expansion pressure chamber, whose organ is located in the highest pressure zone, so that there is an increase and a decrease in pressure alternately, bringing the liquid out of the liquid system to pressure ne introduced into the expansion pressure chamber to produce the pressure increase, when decreasing the pressure is again introduced into the system, in an area of lower pressure, and the work done with the expansion of said pressure chamber is taken advantage of. so that a quantity of a liquid that corresponds in proportion to the amount circulating in the system is introduced into the liquid pressure system.
