The present invention relates to the field of land reclamation and irrigation can be used for drip irrigation of perennial plants in complex terrain.

A device for drip irrigation, comprising a housing with top and bottom plates with inlet and outlet openings and a regulatory element made in the form of a tubular insert, and the body is equipped with side air is a great device is designed to work with muddy water, has a complex structure and requires the use of compressed air for operation.

Known dropper, including the housing and the cover, respectively, with input and output pipes, throttle spiral channel and the rod and the elastic compensator with a Central hole and projections made at the base of the stem, the height of which is greater than the depth of the spiral channel, this outlet has a camera for posting it ledges and edges of the expansion joint when bending them under the working pressure (A. C. of the USSR №1400551, MCI And 01 G 25/02, 1988).

The disadvantage of this dropper is the complexity of the structural design and unreliability when used, as it is located outside of the pipeline.

Known dropper consisting of a housing with an inlet and outlet and installed in it the regulatory body in the form of a flexible porous pad, equipped with a locking washer having a discharge hole (A. C. of the USSR №816433, MCI And 01 G 25/02, bull. 12, 1981).

The disadvantage of it is personalizing each dropper on certain water pressure in the conduit.

Known dropper, comprising a housing made in the form of a vortex chamber with a tangential inlet and outlet openings, a cap 3, 1984).

The disadvantages of the known drip is the inability to self-regulation of the fluid flow at low pressures, complex design and location of the dropper out of the pipeline, which significantly reduces the reliability of the design.

The closest device is adjustable flow limiter for drip irrigation (U.S. Pat. Of the Russian Federation No. 2124830, CL 01 And G 25/02, 1999), comprising a housing with an inlet and outlet; a channel formed by two opposite walls, one of which is made in the form of an elastomeric membrane and can move relative to another. When this channel is equipped with reflective walls positioned across the channel throughout the length of the perpendicular from the fixed wall to mobile (elastomeric membrane). The channel consists of two labyrinth formed by reflective walls and following each other. One of the labyrinths is determined by the reflective walls having the same height equal to the height of the gap of the channel formed by the fixed wall and the movable (membrane), and the other maze is determined by the reflective walls with decreasing height along its length, thus forming a channel with the growing gap between the g is trojstva is the inability to maintain uniform water flow at low expenditures and large pressure drops in the pipeline when using it on a variety of terrain, that reduces the effectiveness of its work; the design complexity and large size; the complexity of Assembly and disassembly of these devices in the pipes of considerable length with a given pitch and a given distance; the difficult process of cleaning the working cavities of the device from clogging and various deposits.

Object of the present invention is to provide a new design droppers, providing self-regulation at all costs and pressures in the pipeline and the pressure changes in the pipeline in different terrain.

The technical result is to increase the reliability and efficiency of the drip.

The technical result is achieved in the new design dropper, comprising a housing with inlet and outlet openings, the elastic membrane, the upper part of the body is secured to the wall of the pipe and the inside of the pipeline is part of the housing with the regulatory body, including the channel and the chamber, which is arranged to control the cross-section height by bending an elastic membrane, and the body of the dropper is made of elastic material, the channel of the regulatory body has the shape of a sine wave and elastic member which allows you to place it inside a pipeline of securing the upper housing to the wall of the pipe. Thus, the inside of the pipeline is part of the housing with the regulatory body, including the channel and the chamber, which eliminates mechanical and atmospheric influences on him and increases the reliability of the dropper. The regulation of fluid flow is achieved by the regulatory body, which includes a channel-shaped sine wave, and a camera with a variable height cross section due to bending elastic membrane overlying the channel and the chamber in the pressure difference arising from the passage of liquid through the channel. Run the drip of the proposed design allows to use it at different pressures in the pipeline and difficult terrain, which increases its effectiveness.

In Fig.1 shows a dropper, General view; Fig.2 is a view As in Fig.1.

The dropper includes a housing 1 with an inlet 2 and outlet 3 holes, with the upper part of the housing 1 mounted on the wall of the pipe 4, and the inside of the pipeline is part of the body with regulatory authority, including channel 5 and the chamber 6, which is arranged to control the cross-section height by bending the elastic membrane 7; case 1 made of an elastic material (rubber-based rubber General purpose), ctih pressure inside the pipe 4, diameter of the pipeline and working conditions; channel 5 regulatory body has the shape of a sine wave, and the resilient membrane 7 is installed with the possibility of overlapping channel 5 and the chamber 6. The overlap of the channel 5 and the chamber 6 is due to the pressure difference arising over the membrane 7 and under it during the passage of liquid through the channel 5, resulting in the regulation of fluid flow and thereby increases the efficiency of the dropper. The location of the housing 1 with the regulator inside the pipe protects it from external influences, which improves the reliability of the design.

The dropper works as follows. Fluid through the inlet 2 flows into the regulatory authority, including channel 5 and the chamber 6. Channel 5 has the shape of a sine wave and the passage of fluid through it can provide the required pressure difference in the pipe 4, depending on the length of the channel 5 and the chamber 6, which has a variable cross section due to bending elastic membrane 7. With increasing pressure in the pipe 4, the difference in the mean pressure in the pipe 4 and the chamber 6 will increase and the elastic membrane 7 will bend and restrict the flow of fluid through the regulatory authorities the progress of the liquid at any pressure in the pipeline under difficult terrain, reliable in operation due to the location of the governing body of the dropper inside the pipeline, which eliminates mechanical and atmospheric influences on him.
