ABSTRACT:
To provide for constant and easily adjusted flow rate of liquids from a container (5), which may be a flexible bag, an indexed feeding chamber (1) is directly connected by gravity with the liquid container (5) and provided with a tubular passage (12) therethrough communicating with the outside, preferably through a filter at an end and with the chamber bottom at the other end. The bottom of the feeding chamber (1) is connected to a dripping tube (1A) positioned below, which in turn communicates with the inlet (21) of a device (2) for the microregulation and stabilization of the liquid flow rate. This device, essentially consists of a holder (44) with a cavity (51) therein and two tubular inlet (41) and outlet (47) passages connecting said cavity with the outside, and having a flexible membrane (43) removably covering the opening of the outlet passage within the cavity. Device (2) is height adjustably supported by a slider (31) on a scale (3) fixed to the stand (4 ) which supports the liquid container (5).
