Abstract

Subject of the invention is a controlled flow limiting equipment used mainly for watering of plants built into a rigid housing that contains a gel the volume of which depends upon its water content and a watertight elastic body wherein the membrane holder (5) mounted on the cover (6) is connected to the rigid housing (7) in which the one or more membrane (4) is placed next to the perforated plate (8) and the watertight elastic body; flexible tube (2) connected to the water inlet (A) and water outlet (B) and embedded into gel (3); or plate (10) on one side of which the gel (3) and on the other side is the switch (9), its wires (11) are connected to an electric valve or tap too.
