FIELD: machine building.SUBSTANCE: invention relates to drip irrigation. Pipe (4) contains dosing elements (1) inserted into it. Elements (1) are connected to wall of pipe (4). Each element (1) includes input areas (2), dosing areas (5) and output areas (6). Through inlet areas (2) water is supplied from pipe (4) into dosing elements (1). In proportioning areas (5), the flowing water pressure is reduced. With the help of outlet areas (6), water through outlet holes (7) located in pipe wall (9) leaves pipe (4). Output holes (7) have shape of slot (8). Edge regions of slit (8) are supported by support means (10) such that folding edge regions (12) of slit (8) inward towards dispensing elements is limited.EFFECT: preventing contamination penetration into metering elements of the pipe.10 cl, 30 dwg
