ABSTRACT OF THE DISCLOSURE: Hydroautomatic valve comprising a cylindrical hous- ing which is mounted vertically and in its both ends there are provided a rigid upper and bottom ring-shaped rest between which, inside the cylindrical housing, there are disposed freely and interconnected an upper and a bottom face closure members. The upper face closure member is shaped as a disc with a hole in the axis of the cylindrical housing and has small legs arranged along its periphery vertically downwards, which end in its bottom end with small teeth turned inwardly towards the axis. The small teeth are disposed freely in a shallow ring-shaped groove in the surrounding surface of the bottom face closure member, which is shaped with a conical peak in the axis. In the bottom end of the bottom face closure member there is machined a deep ring-shaped groove. This deep ring-shaped groove is connected via parallel to the axis holes with the space between the upper and the bottom face closure member. The cylindrical housing is connected via the central- ly disposed in the vertical axis lateral inlet hole and via an outlet elbow above the upper ring-shaped rest to the basic distribution piping of the sprinkling irrigation system, and via a chamber with lateral outlet hole, disposed underneath the bottom ring-shaped rest, it is connected to the piping branching. In the bottom of the chamber, coaxially to the cylindrical housing, there is mounted a cylinder with a pis- ton pin. The space of this cylinder underneath the piston is connected via a hole to the additional control piping of the sprinkling system.
