ES230164A2 - Improvements in the dosing appliances designed to introduce graduable amounts of liquids in a system of circulating fluids under pressure (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improvements introduced in the object of the main patent No. 230.163 by "Improvements in dosing devices intended to introduce adjustable quantities of liquids in a system of circulating liquids under pressure", whose introduction is in linear dependence with respect to the amount of liquid circulating in through the apparatus, consisting of a device for achieving a pressure difference between two points of the system of pressurized liquids, a driving member that depends on the flow through the apparatus and a closure and distribution organ, actuated by it, for the production of different pressures, with the purpose of modifying their volume, for which purpose the work done for the introduction of a certain amount of liquid in the pressurized liquid system is exploited, as claimed in the aforementioned main patent, characterized by the fact that the distribution organ, actuated by the actuating organ nto (3), preferably a distribution ring (5), is arranged in a chamber (51) into which communication pipes (52, 53 and 54) open with the highest pressure chamber (2), with the chamber of lower pressure (7) and with the expansion pressure chamber (12), of which the first two are closed, or alternatively open, periodically alternately, and because the expansion pressure chamber (12) operates a distribution member, preferably a regulating valve, discharged from pressure (56), through which the inlet and outlet of pressure liquid from the pressurized liquid system is distributed to a second pressure chamber (63) of alterable volume, which a pumping device is actuated for suction and transport of liquid from a container (73) in the pressurized liquid system.
